Yes we will have regrets as we get older but we also need to let these regrets go. We need to forgive ourselves and move on. Regrets only hold us back.
If it's something you think you can change then do so. Take that trip, make contact with that family member or friend, do that degree, change jobs, whatever it is go for it! You are never too old for change.
So for today ask yourself: Can I do something about this regret or do I need to just let it go?
