How do you cope up with when you get to know that you have taken wrong turn at every nook and corner of your life, every crossing of your life.

Stop. Pause. Think about what has happened. Did these things happen because my action or the actions of others? Take a moment to think what do I want to happen, figure out how to get there, then take the first step in that direction, and then another…

You stop the negative thinking and judging yourself, and continually looking in the rearview mirror, pay attention to where you're going, stop comparing yourself to others, and make plans to look forward, and move straight ahead to the future. You will never move forward until you stop looking in the past. It's not necessary. You're not going that way. I refuse to live my life in the past or according to it. It's nothing but a dead-end!

I don't actually believe there is a right or wrong direction to take.
So long as we learn from each turn.
Life is supposed to be all about the journey. What's a good journey without a trip through the bad part of town.

Recognize your faults (which you have done) and be aware you can’t change the past. and use them as tools for betterment for your future from this point on
