You won’t be haunted by the spirits of people who have passed on, but you will be haunted by every decision you made for the wrong reason.

The thing to remember is that you can’t change any decision you made in the past. However, you can promise not to make any more bad ones in the future, and if you’re very lucky, you will keep that promise, but that’s unlikely, too, because you don’t have enough experience to only make good decisions. I’ll leave you with one final thought.
You’ve got to experience life to understand what it means to be alive.
