If you read the last post of mine, I have talked about how powerful time is. We can win against anything, but not against time.
Patience is that quality which makes us respect the above mentioned fact. It makes us respect the importance of time. The only way to not let time defeat you is by making friends with it. And the only way to do that is by imbibing patience inside onself. Once you have done that, you can win everything. Anything.
