Start with a hobby.
Model trains?
That isn't quite the "real" feeling I am after. A hobby that only benefits myself because I am bored doesn't seem like the kind of thing that will fulfill my lack of tangible real problems to work on.
The fact that my model train stopped working because the motor got wet or whatever doesn't really seem like an important problem to solve that would benefit anybody in particular.

They only ask for donations, fundraisers, or to join their newsletter. Is there any actual work to be done?
