I wanted to have this small post for a long time.
One small lesson, I learned in life, which turned out to be the most difficult skill or character to have is "assertiveness". No show of undue emotions, no prologue or epilogue, no intimidation, no explanations, no fear or threat. Just simply stating the fact and speaking up of mind.
I guess, I can't describe, that's why it took so long to do this simple post!
