Edit Title mistake, I intended to say, "How do I maintain discipline".

I get the impression I can get much more out of myself than what I am currently am producing. Because I have random bouts of motivation to do tasks I need doing. But how can I create that iron discipline the best men in every field has? I want all these improvements but what is the best guide, the best formula to maintain that commitment?

Advise, articles, and research etc you have on offer I would love to see it. As it would help myself and the TRP community.

Thank you
