Do we make same mistake again and again?

Funny how one thing leads to another. When you put your brains to work, how much we think and how far we wander, crap of course(for me). I kept thinking how we keep doing same mistake again and again, and i was wondering, if we know we did this before and its a mistake, why do we do it again? Better, how did we manage to fall in same hole that we know for sure we closed it (figurative speech).
              Is it 'coz, we know, we can get out of it easily or may be just maybe its not a mistake at all or may be we do not want to accept its a mistake, because someone said it. If you look at it closely, each circumstance has its own reason. Wisdom, we think we did it before so we can get through it easily, Social Elements, convincing us, what we did is wrong (10 out of 9 people saying its wrong makes you doubt yourself) and finally Conscious, "i know i am right" feeling.. Things happen for a reason, is what we were told always and we always gave that excuse if anything happened, good or bad. We need that belief to go to next step. But what if we are just going in circles? There are many among us (i feel like i am one among them) who are going in circles and tripping over the same step, may be in a different way every time... but surely tripping at same step..Sometimes you feel like everything is going perfectly, is it possible that its because we are doing the same mistake, since we been this way before or we are really in right path? Should we stop for a moment and think or just keep going... like they say, take the risk :).  Now how do i distinguish between those two.. whether the way i am going is the way??? How do i avoid making same mistake again and again? Like the saying goes.. Fool me once shame on you, fool me twice shame on me. Unfortunately, in this case, i am fooling myself.. In any case i am the one who should be ashamed off.
             At any point of time in our lives, there is always one person common for everything thats happening.....No, its not God, smarty pants.. its You ... Like it or not.. we do make mistakes again and again, whether you believe it or not, agree to it or not. We are creatures of habit and we tend to fall on the same path and follow it..May be 'coz we are comfortable that way but i guess the real question is not whether or not we make same mistakes again and again but how better were we this time around? Well with that thought my friends am going to bed..
