Singing! In the past couple years I started taking singing somewhat seriously, finding songs that are in my range and trying them out in my car. I'll record myself on my home from time to time, it started out sounding terrible and nasally, but the more I do it, the more I get used to my voice (important) and the better I get at using my diaphragm (more important). I didn't use my price much growing up, because I just didn't talk a lot of the time, but singing has definitely helped. If I need a boost of confidence, I'll put on a song I can sing decently well while driving and sing along. I'm by no means good heat, but I've come a long way
