Ask HN: Should I go back to academia?

I'm 30 and have worked as a software developer for the past 10 years. Travelled the world, worked with amazing people, and for inspiring companies. I don't regret any of it and have learned a tremendous amount during this time.

Recently however I've been feeling a bit burned out and the idea of doing something for myself (and nobody else) such as studying, has really inspired me to take a deep look at my life and see what I should be doing about it.

I can continue doing software development, which will involve working for others of course (as most other jobs require). Or I can of course start my own business, which I also tried and seemed like in the end I was still doing things for other people - after all, markets are driven by users' needs.

After thinking about it some more I thought, why not go back and finish my CS degree? I have about 2 years left (have 2 left from my younger years which I can reuse). I saved up enough to afford it - fortunately here in Europe university is pretty cheap. It feels like it will be one thing I can do for myself and will not regret. I'm a bit scared about leaving industry and not being able to find a job once I'm done, but I figured, I'm not going to study gardening - a CS degree could perhaps give me even better experience than other 2 years of "burned out" industry.

I was wondering if any of you have had these thoughts as well (mostly doing things for yourself, like studying) and whether you think going back to study is a good idea or not.
