“ I'm afraid that no one will hire me because by the time I've graduated I'll be 35. Who wants an old guy working at an entry level job. Plus, if I decided to pursue my education I'm afraid that I can't blend in with all the young students.”

These are all your irrational fear. It doesn’t materialize yet. Even if it is, just persevere. Trust me, try your best at formal education.

Don’t go the gig economy route (grab/ etc) because its not sustainable long term.

35 years old, still consider young.
