Don't well on the past, you can't change it, but what you can change is the direction of your future. You've learned a valuable lesson the hard way: that time is the most valuable resource, that you can't get it back and that it is non-fungible. Some people don't learn that until it's far, far too late. You've learned it early, use that knowledge to direct the rest of your adult life.
