Action/Inaction

I have recently discovered that sometimes action in opposition to the consequences can leave one just as doubtful and regretful as deciding to not act. I act out of fear of what could have been, it could be summed in the "Live with no regrets" statement, but maybe this is not the best idea. I have come to conclude that one cannot know when a decision to act will be a decision that will lead to regret; or the contrapositive to that. Therefore I think the decision to act hinges upon whether or not it would be wise to do so. This sounds obvious, but wisdom is logical and emotional at times, but also is transcendent of both. So the question is what is wisdom?
