To myself as a child - Ask my mom to homeschool me from 3rd to 8th grade, then put me in high school whenever I was ready. (I went to 7 schools from K-8th, often changing halfway through the year, so I think I would have fallen through the cracks even if my parents had been paying attention.) Tell my parents to also accelerate my older brother somehow but leave him in school. To my older self - pick a more challenging college, good grief.

I wonder/worry about what mistakes I'll make with my kids. I'm afraid that I'll lean towards certain decisions with them based on what I would have wanted as a child. Hopefully not, but I have promised myself that I'll pay close attention to their education, talk about things with them, and not assume that quiet = happy.
