No Pain No Gain

Some people say that Pain is a GIFT.

Or, that WITHOUT PAIN, there is NO GAIN.

Or, that PAIN is a CATALYST for massive GROWTH.

Yet others say we need to FAIL, and FAIL, A LOT.

And by FAILING, they are referring to a process of EXPERIMENTING, actually.



So, might we talk of a DIFFERENCE, between mere EXPERIMENTING, to gain knowledge ("failing"), vs knowledge gained from MASSIVE PAIN- inducement":  which we would also typically call a FORM of FAILING, too?
