Let It Go!

With all the conflicting "let it go" vs. "stick with it" advice out there, how do you personally decide when to keep holding onto something and when to finally let it go?

If I knew the answer to that question, I am certain my life would be better by degrees. I tend to hold onto something, even when I shouldn't, even when it is emotionally detrimental. I think the correct answer would be to use logic instead of emotion. Unfortunately, I don't seem to be capable of that.
