Your beliefs become your thoughts. Your thoughts become your words. Your words become your actions. Your actions become your habits. Your habits become your values. Your values become your destiny.  Mahatma Gandhi

Another way, similar, of saying this is that our thoughts really do create our reality. 

I have always said, "Think it - Feel it - Say it out loud, to yourself - repeat it daily all week - and then - Do It.

Once you know, truly know, your real Purpose (in life and in work and in recreation - they should all match) then nothing will stop you.

Watch the video "Full Out" and you will see what I mean.
