I'd push myself to do more things.
I regret the things I did not do more than the things I did that I probably should not have. Nowadays, I do push myself to do things that make me nervous or scared or make me wonder what people will think about me if I did do that. Turns out, everyone is minding their own business, thinking the same thing.
Then again, hindsight is a beautiful thing.
Hi, past is for Future -- not Future for past.
I wouldn't escape the English Classes, when I was a boy.
If I had the same dedication maybe today I would be fluent.
