throwing sidearm

Question
First of all I would like to say that my mom, Sylvia,  remembers you.  She graduated from Plainview High School in 1987.  In 1990, she got married to my dad and moved to the Houston area and I thought it was weird how you live here too.
It is so cool to find out that you taught Carl Crawford.  He is an excellent player.
Anyway, my question is: How can I stop throwing side-arm?  I try to not do that, but it gets hard and I get used to it.  Please help me figure out how to stop.
I have been playing baseball since I was 4, I am now 11 and dream of playing for the Astros one day.  Thank you for your time.
