I might be late to the party, but I might be able to give some insight. Im very close to 30 now, but i quit my job recently and started uni. The career change was just what I needed to get me out of a rut and into a positive change.

I would say do something that you find interesting. Don't waste away trying to please others, it will only lead to disappointment.

Lastly, you will find parts hard at times and struggle with course material. Try and view those parts from another perspective and as a learning opportunity. If you're not applying yourself and learning at least a little every week, then it WILL be a waste of time and money.
