Okkkkkkkk.... I'm just going to say when I was 23 I started nursing school. And a big part of me thought wow I'm too old for this but I really self reflected about the "issue" and came to realize that IT WASN'T ABOUT AGE at all! It was about my views of success.
Maybe I will hit home with this for you. MY FRIENDS and boyfriend had all graduated college by this point in our lives, working successful jobs in their field of study or going on to grad school! I saw them having success and felt left behind. While of course I had my own personal success it almost didn't feel on a common ground with their career successes. While I was working full time and going to nursing school full time and taking care of my kiddo, they were done already!! Talking about their lives, getting engaged, buying houses. So I felt that I was "too old" to be in school still, that's how I manifested my frustrations!!!! But OMG!! Your young girl! Don't let anything old you back! Follow your dreams at any age.
Now at this point in my life I realize there is no comparison!! My bf is about to be a cop, one friend in marketing/graphic design, one is a stenographer, an electrician, a loan officer.... We all have great careers that are in a wide variety of fields and we are all still young!!!! Although I must say they do find my career much more exciting!!! Whether I finished a few years behind or not.., they gave lots of support!
There's no such thing as "TOO OLD" only excuses to keep you from not doing something! Good Luck!
