When I become older...I will regret when I was younger

Yew look back at the last year and yew can’t believe that it flew by so fast. Yew look back at this last year and yew think about the things yew did, the things yew didn’t do, the things yew said, and the things yew didn’t say. Yew think about these things, then yew pause and yew wonder: if these things happen again, would I react the same way like during this last year? Or would I do things differently? Would I have spent more time with my mom? Would I have partied much more with my friends? Would I have done more effort in my studies? I think I would. And this is scaring me to know that only after one year, I am already regretting the things I did and/or didn’t do. So what about after 30 years, when I become 54 years and I look back at myself when I was 24…how many things will I regret then?!!!
