You shouldn't look back, but look forward instead. At 23 you should have most of your life still in front of you. At 57 I'm painfully aware that I don't have all that much time left so I'm trying to make the most of it, there is no reason to wait until you are old to start realizing that your time on this rock is finite. At least you realize it now, some people never do, and I hope that you had some fun.
Stop ‘wasting’ time as you see it.
Keep it simple, and it will be easier for you to stay on your chosen path.
Now for a bit of advise from an older man who ‘wasted’ his youth. Life will give you challenges, and consider carefully how far away from the tree you strive. There is hidden jeopardy in the unknown. Who can you turn to in times of crisis? Who can you trust? To whose advice will you listen? So, make peace at home and with your loved ones first before you take on the world outside.
