This whole journey of life is like a cricket match, where only one player is batting and that is you.No wickets, no wicket keeper, no fielders and no umpire also It means you can't be out unless you leave the ground.Life is throwing opportunities like as cricket balls.
It's ok, if you miss one, two, three, four or even five (Remember, you can't be out), but when you hit the last ball for six, all that damage happened would be recovered.
So failure is just like those missed balls, the opportunities that you couldn't grab. That should not be the end. Don't worry if you missed one over also. Still many more overs has to come. You just have to pick the right ball and hit for six. The only way you will get failure in life is, when you leave the stadium.
In simple words: Failure is, when you lose your hope and quit
the journey. So chill out and keep hitting sixes.I will tell one thing, whatever happens in life try to be neutral, stay calm. If you got success don't get so excited because it is also not permanent;if you closely watch people who are succeed in life, you can see they will stay neutral in their bad and good situations, because they know the failure or success is not going to be with them forever.
What you fail at does not define you. You define you. You are capable of achieving great things when you rise above adversity. Let the things you accomplish define you, nothing else.
Good luck,
Make yourself proud.
