( CNN ) Hillary Clinton 's campaign-in-waiting met on Saturday in its Brooklyn headquarters , a day before the former secretary of state officially announces her campaign for president , according to a Democrat who attended the meeting . Robby Mook , Clinton 's soon-to-be campaign manager , distributed a `` values statement '' at the meeting that outlined what the campaign will stand for , what their goals are and how they plan to win -- something Clinton failed to do in 2008 . The campaign 's purpose , the document states , is `` to give every family , every small business , and every American a path to lasting prosperity by electing Hillary Clinton the next President of the United States . '' The document makes clear that the campaign will try to avoid mistakes that plagued Clinton 's failed 2008 run . Many of the `` guiding principles '' in the memo mention issues that sunk Clinton 's first campaign . The document , according to the source , includes the ideas from Mook , along with a wide array of Clinton 's soon-to-be staffers and advisers . The memo maintains that the campaign must remain humble , disciplined and united , something voters in Iowa and others states have said Clinton did not do in 2008 . `` This campaign is not about Hillary Clinton and not about us , '' reads the document that was obtained by CNN . In the section about the campaign 's guiding principles , the document reads , `` We are humble : We take nothing for granted , we are never afraid to lose , we always outcompete and fight for every vote we can win . We know this campaign will be won on the ground , in states . '' It also calls on campaign staffers to remain `` disciplined '' and `` open to a diverse range of views . '' `` When we disagree , it 's never personal . Once a decision is made , we execute it -- together , '' reads the memo . `` We know there will be tough days , but we will bounce back and get back to work . '' The document also appears to telegraph the name to Clinton 's campaign : `` Hillary for America . '' Clinton is planning to launch her presidential candidacy on Sunday through a video message on social media , according to Democratic sources . Shortly after her announcement , Clinton will travel Iowa and New Hampshire , critical early caucus primary and caucus states .
