wisdom?

in reflecting on the past months and years, i have been thinking of things that i wish i would have done differently, things that i would have done exactly the same, things i would have done--but would have gone about them in a different manner than i did previously.

is that part of how wisdom is gained?--of learning from previous experiences? i do not know if that is how wisdom comes about or not, but i do know that it will be a life-long and continual process.
