If it's about business meetings... Think about everything that happened, every single phrase you said, and think about peoples's reactions towards it, think about every single person present, how do you remember his/her reaction to your opinion, write down on a paper which people you really influenced and who you didn't, revise your mistakes as everybody does some, and plan for a better meeting next time.. And think about how you'll be able to persuade the people you couldn't last time...
