If I still at Malaysia, I will not have chance to take public transport everyday. But now I at Singapore, and do not have enough money to have a car, (car is a luxury here, for me), I had to spend around an hour everyday, taking bus, train, then bus again to reach office.
So I meet a lot of people everyday, listened to their conversation. And as expected, 90% of their conversation are more toward complaining. Complain about boss, colleagues, life, house-owner, etc. Ya, life is never perfect, and we have tons of reason to complain, when things turned against us. But there are so much of wonderful things happen everyday too. But people tend not to discuss about that, maybe complaining will bring sympathy from other people. People like to be comforted.
But, when u see teenagers, they are so happy normally. Chit-chat each other, playing around, talking about wonderful things, etc. We had time like them before, but since when we start to lose our sense of being happy, always look things at negative perspective, not considerable, etc? Life pressure changed us? I dunno.
Life should be wonderful. Being alive is already wonderful enough.
