I heard this from a friend.
I would like that question that belief, what if you failed ever before you started? You spent all that time, effort, money - things that don’t come easily to you; suddenly that magic carpet you were weaving just rolls off your feet!
You try again and again to build it back up: Funny it is, this thing called life! It doesn’t let you start and it makes you quit cause you run out of resources even before you get the chance to fail.
Having the opportunity to FAIL is a luxury!
Starting from a deficit of resources, you try to close the gap between your needs and your ability to dream of goals. This is why I take everything as a one shot win or lose game! Try again only if you have the luxury for it.
