Dani and Julia, it's never too late change careers if you really want to! I met a gal in Spanish 1 my first day at the community college here in Austin. We were both going back to school after a years long break, except I was 25 and had no kids, and she was 37 and had 4 kids! The youngest was 5. It was more challenging for her of course, because she would send the kids off to school, run to classes herself and then run home so she could be there when her kids got off school. Both of our goals were to transfer to the University here, which is notoriously difficult to do. GPA is really paramount. We ended up in the same Spanish 2 class as a fluke, and then planned to take 3 and then 4 together, and we became friends. We both applied to UT and we're both starting this fall together! I'm so excited. Even though we'll be in different programs, we have classes about the same time, so we plan on getting together a few times a week for lunch or to study. She worked while her husband was in school, and then was a SAHM, and now she said that it's her turn to get her degree, which she always wanted to do, and it's really an inspiration to me to see her follow her dreams and still be able to be a great mom and wife.
Sorry, long story. I guess my point is I really think that age is just a number, and if there is something you find that you really want to do, I just know you can do it. Plus, you might end up inspiring people you never thought you would before.
P.S. Patience, I really like this new system. If it's below a 6, then we can just give an explanation like we do now as to why maybe it's not the most flattering thing, etc.
