Back In Time ...
 

I'd go back to when my son was a baby or a toddler, or even an elementary-school kid. I'd spend more time with him, take more pictures. I'd read more to him, pawn him off onto babysitters less often, let him fall asleep in my arms while I'm reading more often.

I'd go back to when I was 17, 5'11", and 145 pounds when my brother called me fat ... I'd tell him to stow it, because I wasn't fat. I'd tell my dad to praise me for my attitude and my actions, not for my appearance, because that would cause mucho damage throughout my teenage years and my 20s. And 30s, in fact.

Finally, I would have done slightly better in college, graduating with honors instead of graduating with a decent GPA.

And yeah, I should have been nicer to my little sister when we were kids, too.
