The open secret to fulfillment and happiness is to help other people.
Now the problem is how to do that.
I've done some IT support but this basically comes down to reinstalling Windows a bunch of times (e.g. after ransomware) or telling people they should, after ten years, really be upgrading to a new computer (for which they don't have money) rather than trying to get me to fix it up. Wasn't that fulfilling and the pay is pretty mediocre even for student standards.
I'm good at two foreign languages, perhaps I could teach people that?
Or rather do volunteering part-time? Question would be what to do, but not getting paid would probably make it easier to broaden the scope beyond specific competencies.
How to go about the actual execution without a huge pay cut is where I think advice would be most helpful.
