Are you depressed ?
If you have never failed, you have never lived.
If you failed, don't worry about it. It's OK to fail.
Life is all about taking risks and trying again and again. We learn from the mistakes we make.
We must fail first to get to the success we wish for. Because this is how we learn in life. This is how we achieve better things.
So don't give up.
Stay motivated and never worry. :-)
