Getting ready for college, next step in life,

I have been quite busy, trying to run around, buying things, (mostly buying things, which I can ill afford to do), getting myself a decent pair of walking sandals (gosh, they cost $49, on sale), preparing to go to college. It is hard to believe, at 50 something, I am going to "live" at college and get a Masters in English. Why do this? Like Dana Torres, 41, Olympic swimmer said, it's never too late to achieve your dreams.
Yes, you can go to college, even if it will be the same one as your son! But he is an undergrad in IT, and I hope to be a professor or editor/research writer. And to keep writing my satire "Lessons" on the side.
Even drove up there for an assistantship job to help with student activities, but, well, they gave it to someone else, someone no doubt younger. But son says "he" could get me a job!
Maybe I could be like Lee Smith: professor/author. It is one goal, anyway, along with improving the environment for plants AND people, and help support public school teachers. I just need to be better at picking myself up in the job-setback department. There will always be fierce competition (so how do you get "picked" for things)?
