But what I learned the last few years is that I don't miss the things that I thought were "living" when I was young. Drinking or "Nights out" is one of them. Also: Everything "Internet" (Netflix, Youtube, News, ...). Especially when it actually hinders me from experiencing life (it will steal your day).
That does not mean I regret anything. I made my experiences, everyone should, I think this is an important part of growing up for a lot of people.
Nowadays, eating healthy/well, exercise, etc. are the things that make me feel more alive and well - these are the things that make life "better".
But also I have two small kids, so there is no time and space for all these "silly things". And for the same reason I eat to much crap and don't exercise nearly enough for my taste. And I watch way too much YouTube.
Moral: Do your best and try to enjoy it. Nobody can tell you if the bus is waiting for you the next corner. But wether it changes anything if you are drunk at the time is up to you.
