Remember water start turning smelly when it stops flowing. Same rule apply to human being when you stop yourself you start rusting your abilities, ur skills ur qualities ur intelligence. Being stagnant means the door of improvement and opportunities is shutter down by yourself. .
So, it does not matter whether you win or lose. Because it's life and sometime you will rise and sometime you may fall. But you only fail when you stop trying.
So you need to try try again. Don't think about the failure because you never know when your prayers and hard work will get answered and you get rewarded more than u ever thought and imagine. In short, keep trying!
