"If you are not prepared to be wrong, you will never come up with anything original". Does this apply to education OR to profession?

I will ignore the two you gave and say it applies to any situation and scenario in life.We stumble and in the process we meet or encounter what we are after.

It applies to everything - if you fear being wrong, you will not produce anything original because, since it is original, you will not have a way of knowing whether it is right or wrong. And since you are not  prepared for the possibility of being wrong, you will decide not to come up with it.

I agree that it probably applies to both, and more.  How many business plans have you seen whereby an entrepreneur will just copy what his neighbour is all ready doing?  There was just enough business for the neighbour to eat, but now two families starve.

One of the single most important lessons I learnt in life was "learn from your mistakes"! If you put this "lesson" into the context of your question I would suggest that you are accepting that sometimes you will be wrong, realising that and learning from it, applies across the board to ANYTHING you do in life!

education

A profession without question.

because in every workplace you go you got mistakes and if you're intelligent you'll not repeat them again in the next workplace and so on.

KHATIM BRO, it applies over all the life span,,
