But does it matter?
Our rat race society has produced too much unnecessary stress. Norms are man-made. Life is meant to be fun. There are some who run around to earn breads for the dining table, and eventually found that no one appreciate the breads. Life is ironic. The more you want, the less you get. Eventually, in a blink of an eye, you noticed life is after-all will come to form a circle. You sow, you reap. You want a quality life, you'd better work towards it now.
What I want in my life is simple, I want to wake up every morning knowing everyone around me is happy; and I smell the crispy sunlight in the morning and fragrance rice in the evening. Life, is not about fly or not fly. You can still achieve a lot even if you are not flying.
You just have to work on other alternative strategies.
