I have done nothing significant in life yet. Have not helped anyone or improved the world at all in almost any sense. But still it took me a lot of practice to get to where I am now. I am confident I can do it again and again given same amount of time and same attitude to life from same or little more limits I had and starting from any timeline from 1980 to 2014. Only thing it takes is same amount of practice. This is probably true for 99% people living today. I am curious if you feel the same way. If you are given back your time and energy but taken back everything else, can you repeat what have you done? Say, starting today? If yes, how much more limits can you overcome? I have a lot of admiration for you. I consider you my mentor (book, article and other works). This is not to challenge you or anyone- just trying to understand what successful people think about luck, environment and timeline.
