Living my life now and looking back at what I've done of course you would say you could have done things differently but I have never regretted the things I have done and or I haven't done (of which I am trying to reduce). Leap of faith is always needed I think. I guess I want to have a point where I go back in time and talk to my own self where I tell about my life and realize how much I have grown in a holistic nature. Just need to fix some kinks on the time machine. Maybe I need to estimate the quantum effects to lead a measurable violations of the null energy condition. But that's just a small matter. Ha ha.
If you have any idea on what it is I am trying to say, congrats. You must have a Phd. Perhaps you can tell me as I don't know myself.
