She shares five lessons she learned as secretary of state, sounding a bit Mitch Albom with the upbeat adages. ("Leadership is a team sport." "You can't win if you don't show up." "A whisper can be louder than a shout.")
She reminisces about her mother, Dorothy Rodham, and tells the oft-shared story of the first time she heard her husband's Southern drawl as he described "the size of watermelons in Arkansas."
She will stick around for handshakes and picture-taking, but that must be negotiated as part of her fee, estimated at upward of $200,000.
Former Secretary of State Hillary Rodham Clinton is hitting the paid speechmaking circuit, drawing huge crowds of conventioneers from groups like the American Society of Travel Agents and the National Association of Realtors.
She is joining what has turned into a lucrative branch of the Clinton family business: Bill Clinton earned $13.4 million from speeches in 2011, according to financial disclosure reports, and has collected more than $100 million in speaking fees since leaving the White House. He brings in as much as $700,000 for a single address, an amount he collected after he appeared before a company in Lagos, Nigeria.
The events are also giving Mrs. Clinton large captive crowds as she considers a run for president in 2016. She often indulges her inner policy wonk, along with the softer family chitchat, according to several people who have attended her speeches this summer.
Last month, about 17,000 people lined up just after dawn outside McCormick Place, a convention center in Chicago, where Mrs. Clinton, in prepared remarks, talked about health care changes, as well as border security and immigration. "I hope it's heading to a new law that will resolve a lot of these issues," she told the crowd. "It's way overdue."
She praised the human resource managers gathered for their conference. "You know what it takes to provide workers the flexibility and benefits that they need to care for their children," she said.
At a time when almost everything Mrs. Clinton publicly says feeds presidential speculation, she has also used the speeches to address issues like the Arab Spring, the conflict in Syria and the former National Security Agency contractor Edward J. Snowden.
Mrs. Clinton does not make her speechmaking schedule public, and her spokesman declined to comment.
But her political rivals have already started to keep tabs on her paid speaking schedule, looking for any hint of a conflict of interest. (So far, Mrs. Clinton's staff appears to have carefully chosen where she has given speeches, avoiding paid talks to potentially controversial groups.)
"We're starting immediately to monitor both Hillary and the other Democratic rising stars and collect, tag and characterize their speeches so we can hold them accountable when the campaign begins in earnest," said Tim Miller, the executive director of America Rising, a conservative political action committee.
Mr. Miller said that it was too early to send operatives to covertly buy tickets to Mrs. Clinton's speeches, but that the group was watching from a distance "to monitor whether she's hobnobbing with investment bankers in New York City that might seem like favoritism down the line."
Since Mrs. Clinton stepped down as secretary of state in February, she has divided her time between writing a memoir and juggling a growing schedule of paid engagements, along with unpaid appearances, typically focused on her advocacy work for women and girls as part of the Clinton Foundation, the charitable organization founded by her husband.
In Chicago, she also spoke to a sellout crowd at the Navy Pier to benefit Citizens United for Research in Epilepsy, the nonprofit group founded by Susan Axelrod, the wife of David Axelrod, a former top strategist for President Obama.
Next month, Mrs. Clinton will speak at a meeting of the Global Business Travel Association in San Diego (a convention her husband addressed for $250,000 last June), and in the fall she will deliver speeches at the conference of the American Society of Travel Agents in Miami.
In between, she will pick up awards from organizations like the National Constitution Center in Philadelphia. (Jeb Bush, the former Republican governor of Florida, whose name has also been floated as a potential 2016 candidate, will present the center's Liberty Award to Mrs. Clinton in September.)
As a political image builder, of course, the paid speaking circuit is almost unrivaled, said Tad Devine, a Democratic consultant who advised Al Gore and John Kerry in their presidential campaigns.
"It's a one-way street" that allows Mrs. Clinton to set her own terms, Mr. Devine said. "It's the perfect opportunity to deliver a message of your choosing to who you want, to reach a broad audience and to get paid for it."
A staff of about seven working out of Mrs. Clinton's small personal office on Connecticut Avenue in Washington balances her schedule. Aides include Huma Abedin, the wife of the New York mayoral candidate Anthony D. Weiner, and Ted Widmer, who wrote speeches for Mr. Clinton and worked in the State Department under Mrs. Clinton.
Mrs. Clinton's staff devotes much of its time to digging through giant binders of research assembled during Mrs. Clinton's time as secretary of state to help with her coming book. The untitled memoir, scheduled for release by Simon & Schuster on June 1, will, according to an Amazon blurb, chronicle "Hillary Clinton's candid reflections about the key moments during her time as secretary of state."
A handful of trade groups -- which do not endorse political candidates -- started requesting Mrs. Clinton for their conferences even before she left office, said several of the executives involved in booking Mrs. Clinton.
"We had her in mind mainly because of the issues she was dealing with in the Senate and even as first lady with health care," said Hank Jackson, the chief executive of the Society for Human Resource Management.
The Harry Walker Agency represents both of the Clintons and other sought-after speakers like Kofi Annan and Dick Cheney. Don Walker, the president of the agency, did not respond to e-mailed requests for comment.
Mrs. Clinton's fee of around $200,000 per speech is negotiable depending on, for instance, how long she spends shaking hands and posing for photographs, if she participates in a question-and-answer session in addition to delivering a speech, and whether an organization provides a private plane or other transportation, said one person close to Mrs. Clinton. (Mr. Clinton makes roughly the same amount for domestic speeches, though some of his overseas events brought in several times that amount in 2012, according to the financial disclosures.)
Two groups said that after booking Mrs. Clinton they had to find larger sites to accommodate the crowds. Last year, the American Society of Travel Agents held its annual gathering at the Los Angeles Convention Center and drew about 800 people. This year, with Mrs. Clinton headlining, the conference will take place at the 28,000-square-foot James L. Knight Center in Miami, which holds 5,000, said Zane Kirby, the chief executive of the organization.
Mr. Kirby said that two-thirds of the group's travel agent members were women who owned small businesses, so Mrs. Clinton seemed a natural choice. "People want to hear from her on a more human one-on-one basis," he said. (Mr. Kirby declined to comment on contractual terms.)
Booking one of the country's most in-demand public figures does not always work out. Last month, Mrs. Clinton had to cancel a speech at Pershing LLC's Insite financial conference in Hollywood, Fla., when it fell on the same day as the funeral of Senator Frank Lautenberg of New Jersey, at which she delivered the eulogy. Pershing got former Defense Secretary Robert M. Gates instead.
