How does a motivational speaker motivate himself/herself?

No one can motivate you untill and unless you motivate yourself.

A motivational speaker also needs self motivation to stay charged up all the time so that he can motivate others.

I can answer this question because i am a motivational book author and speaker. And i can share what i do when i feel down.

Well this works for everyone.

Read good inspirational stories of successful people, read motivational books, watch motivational videos.

And even if this doesnt work for you, you can hire personal life coach. They ensure that you give your best shot on every thing you do. They keeps you motivated all the time.

They will help you set goals every morning, and will ask for how much work done till night.
