There could be no more simpler reason for saying this.
maybe it's my logic-based perspective, aka unemotional-ity. but the worst part to me is when you make emotional response to the opposite party, in an uncomplimentary manner, for your own shortcoming. honestly, i was expecting more from you. like, learning from your mistakes and not living in regret. and the last four words means by getting smarter, not more unemotional towards people. because logically speaking ANY blocking of emotions is at one's own fricking loss and wisening up, and minding over emotions, is one's own precious gain of perspective. CHANGE has to be on the right places for a desired CHANGE!
Watch how much your sufferings are, OR, Do until you reach there.
The decision is yours.
