Try not to worry about how you've spent your life up until now. You likely have many, many years left to live your life and focus on the things that matter to you.

I used to think similarly, lamenting mistakes made and time wasted in my earlier life, but as I get older, I now look ahead to eternal oblivion, and realise that in the grand scheme of things these concerns aren't really important.

I just try to use my time as best I can now without being concerned with the past, knowing that my future could end at any moment.

Time spent wallowing in regret is also time wasted.
