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 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.

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.

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

Hard work is vital to success. As long as it's in the right direction!

Never give up in life. Learn to be humble, resilient, honest, wise and submissive and you'll be able to make a change better than anyone else.
