The question I get alot is how do you become a Motivational speaker? The best answer is you just do it. Speak alot, everywhere they will listen, even if you are speaking for free ( however if someone wants to pay you, take their money). Once you get good at it ( 500 plus presentations later) usually people will ask you if you do this for other events,or for a living, and it builds from here.
During a leadership workshop we discussed how leadership spends too much time planning for fun instead of actually having it.
I was the keynote speaker at a conference this week where a delegate asked, "What are good public speaking topics?" Hmmm i had to think about it.
