I think it's okay. There are plenty of opportunities later in life to fall back on a middle class job if your dream doesn't work out. Lots of people don't enter my field (actuarial) until their late 30s/early 40s. You pass some exams and then start applying. The biggest group of older candidates are ex math teachers who couldn't pay the bills with that job, but you do run into an ex poker player every now and then.
