It's normal to regret, isnt it?
Things that you could have done, but didn't do it, it sets you
thinking.
What would have happen if you had did otherwise?
Every single action changes the future.
that is a very bad cycle...
"What ifs" are neverending... U can let ur imagination run loose
but still wont get to think of all the possible options and
outcome...
Embrace the fact, move on with time...
