Why do people Fail ?

Let's talk about failure. Why do people actually fail? Whether its business or an exam or in life.

There are lots of reasons and everyone has its own excuse for failure, but in my opinion, there is only one reason and that is the lack of patience and your target.
Patience really matters. Actually, we fail once, twice or maybe more but that's not the real failure. The real failure is that when you start believing that you've failed. And that's the time your real failure starts because now you are confused about your target.
So keep trying unless you fail your failure.
