If you had one chance to change a past time, what would it be and why?

I would have learned to love at an earlier age. I would also have seen humans for what they really are. both would have saved me a lot of trouble.

I'd have studied harder at school.
My teen years were about hiding. Not wanting to stand out, not wanting to push myself.
Looking back, i wish i had.

It would be my marriage because its consequences has made me unhappy until the rest of my life. :-(

I would have said something different, many times.
