Don't be afraid of Competition,
It is remedy to over confidence.

There is a very old saying that says, "Strike the iron when its hot". So start working on the idea when its young. The more you delay the execution of your idea, more will be your drop in enthusiasm and lesser will be your chances for its success.

Don't get discouraged by present hardships,
They are the reason to your success in future.
"Easy Victory is less valued than a hard one".

There will be a billion people out there,
who will say you can't do it,
Just make sure that you are not in that billion people.

When you innovate,
expect to make mistakes.
When you don't innovate,
expect your competitors to surpass you.

Compete, but not out of envy.
Contest, but not out of hostility.
Treat your rivals with respect;
treat your allies with honor.
