Whether things are going well or going poorly, reflect as to what you could have done differently and how that might have improved your situation.
You can always improve. It’s up to you to decide how much you want to put into something and if it’s worth the effort, time, energy, money, etc.
Whatever your decision is, it’s not necessarily right for everyone. It just has to be right for you. Your situation is different from theirs. Don’t judge how others live their lives – just focus on what you can do to improve yours.
