Who are real motivators?

If there is something you really want to accomplish that should self-motivation. The real answer to this is there is no real motivator when you do the things for your own reasons and not for others that will become long-lasting motivation.

Doing work that you are passionate about with perseverance is your great strength; nobody will be able to stop you from pursuing your goals. Always remember the greatest motivator is belief; when we accept responsibility, everything improves quality, productivity, relationship, etc.

Do you agree with this? If not why? Do things that you love, find motivation in yourself i.e. intrinsic motivation. That will make you great. Don't just do things if someone else wants you to, because at that time you are least productive. 

"Your time is limited so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others drown your own inner voice. And most important, have the courage to follow your heart and intuition."
