When you congregate and lump everything together,
emotional blockage are bound to occur.
It is precisely thoughts like these that breed depression and
stagnation in people's course of direction.
Why would you have to consider your past as a factor into your
present and future? If you probe deeper, would that necessarily
means you are more 'sentimental' as people might claim?
No.
But surely, I can tell you are more easily vulnerable to depression
attack.
There are too much consideration for the mundane.
Each individual carries a tag of 'lesson/s' with them. You accept
them into your life, you receive the lesson in return. After the
exchange, they are gone. You are now questioning their existence,
if there anything more than just the 'lesson' they bring
forth.
I say hardly.
You pick a route.
You walk.
If you have to constantly remind yourself why you walk this
direction and thought about the 'what if' in another separate
direction - you are just making your life miserable.
Life is made in such a way that there isn't a 'Save' and 'Load'
option akin to any one player game - it's more like a MMORPG.
