The question suggests, "What are the best ways by which one can measure his/her success?"
I believe this question has a very simple response to it. The best way... the ONLY way by which anyone can measure success is by first having something by which they can compare it to. If there is no standard, success can't be measured.
So, my question is - what is your goal? What are/were you attempting to accomplish and then we can judge how close you came to that goal.
