It's so great that you're doing this, Reba. This will be a third career for you: am I counting right?
I remember when I was in grad school, feeling frustrated with something, and ran into one of my students while we were each walking to our next class. We chatted a little and at one point I said "I think I want to try doing something other than math [math my field at the time]". She said "Amylynne, don't you think you're a little old?" !!!! Too old to try something new - at 23? omg. I have learned so many new things since then. It's a funny way of thinking that it's not possible/likely. It makes me so happy so see other people, past traditional school age, exploring/mastering a new field, and talking about it! Go Reba
