Absolutely man!
So many things can go different from the plan, and it's not the end of the world. Things turn out best for those who make the best out of the way things turn out.
With the sacrifice thing you were talking about, I see it kind of like a givers gain philosophy, where you focus on giving and because you're a giver, people will want to help you in the future. It comes back to you when you pay it forward.
There always seems to be some way to turn something bad into something good. It may even happen all by itself. I like the giver's gain philosophy you mentioned. I feel like it correlates to what I said in this video quite a lot.
