Trying and failing is simply the way ….

I remember someone, possibly Edison saying, I have not failed 150  times I have experimented in 150 different ways and I believe that trying and failing is simply the way we get to know the problem better if we do everything right the first time we do not learn as much.  Vision and perception are crucial in solving problems or in creation. True perception takes time. it is not instant.And we make mistakes which we learn from.Otherwise we go stiff like unused joints
