under-estimation of self

All your life, you keep thinking may be you are not worth this or you're not worth that. The truth ( no matter how cliche'd ) is that you are worth way more than you think you are. And others view your worth somewhere in the range in which you do. So, deserve better, dream higher. All this self-doubt and there comes this moment, when it starts making sense. when, a true sense of purpose is established. This point in life, comes sooner or later, you just have to wait for it. Like any sinusoidal function, life has its troughs and crests. Its what's helps keep you level headed all the time. Good times don't last, neither do the bad ones.
