We ought to give the best shot in life, yes! The storms will come, it will try to pull you down.
But always remember that failing does not make you a failure, unless you choose to admit that you failed.
My greatest point has ever been from that of Thomas Edison
"Our greatest weakness lies in giving up. The most certain way to succeed is to try one more time"
Don't let the failing define you, if you failed several times, it means you learnt several ways that your invention wont work.
So keep trying one more time, in every fail, try one more time.
Knowing that winners never quit and quiters never win
