>> Try and do everything you can

Ars longa, vita brevis [1]

While I agree that experience by doing is the way to learn, the thing is we have finite resources and time while the things which we want to do are infinite. Which means when you choose to do something you are choosing not to do something else - think of it as an opportunity cost.

And merely doing without reflection is also not useful - and one can also reflect on the deeds of others too so that one can learn without a direct harm to ourselves.

I believe it was Bismarck who said

"Fools learn from their mistakes. I prefer to profit from the mistakes of others."
