Definitely not your physical appearance. Obviously you look like someone, be it your parents or someone else resembling your physical traits quite noticeably.
But what actually defines you and your character, your personality is the sum of all that has gone by in your life till now... the various situations, their effects, your actions and reactions.... That determines your present mannerisms.
But that doesn't mean that one should just keep digging down the debris.
We can never recycle our lives....
Life seems just like a road, rolling below the wheels of a car.
There will be a fork in the road, at some point of time in life.
To the left or to the right? Or maybe turn around
and start once more. But we can't always turn around,
nor can take a short-cut.
We can just keep going on once we have chosen a path....
We all feel like
what if we could re-live that instance, that moment! We could have probably changed it.
But we will always land up here, right at this moment this situation where we are at present.
