This is a continuation of previous post.

When l was a student, l wasn’t very attractive.
But ,When I got results at work,I realized
I just didn’t make an effort before.
I couldn’t try looking for what I like.
I couldn’t try doing anything.
On top of that, when I was a student, I couldn’t sleep that much. But After started work, I could sleep immediately!
I mean that l couldn’t sleep because l just didn’t feel tired.
I should have tried anything more.

When I was a student, I wasn’t attracted to the other students. < this has a romantic meaning 😆

I’m happy to help, please let me know if I can explain anything else.
