LOL.. I don't have 'serious willpower'..
My success upto now is because of...
Burning back bridge(My friend and I have a bet ) + Affirmations + POSITIVE THOUGHTS 'Bombarding' + Use of self hypnosis + Reading Positive books, Listening self help audios..
I am also using NLP Modeling techniques ... Modeling Willpower and determination of Alexander the Great and Napoleon Bonaparte using copy cat technique. It's lots easier to complete 30 days trial than to conquer the world.. lol
