While trying to achieve something big, it is possible that we could sometimes fail. But that should not stop us from trying again, because failure goes hand-in-hand with success. In other words, failure allows you to go back and examine what went wrong, what went riaht, and what should be done differently or in a better way. When thomas edison was looking for the right material for the filament of the electric bulb, he failed several times. But he never looked at them as failures. He simply said, i have not failed. Ihave just found 10000 ways that won't work.
