if i can change my life, which part of life i want?

if i wold = If I would like to be back 30th years old, i willnot = I will not play soccer,
if i would not play soccer thereabout, my knees still be healthy,
but i = I have no regrets, I got into the habit of reading
so i red = I read 80 books for 3 years, and I got into the wisdom of life.

So consequently, i dont regret in= I don't regret something in my life.
I am grateful in my life.
I am grateful every day.

That is so wonderful. Thank you for sharing, Byounchul.
