That's a good point and I mentioned it because you included social work in your list of hard careers so thought hard doesn't necessarily mean doing hard math/logic/etc.

I think social work is a hard work "lifestyle" but also hard in the sense the problems you are trying to solve are very hard. In banking / consulting advisory work, the problem is making the client happy, which is not easy but not as hard as rapidly scaling a software system, or "solving" the problems like ptsd or homelessness that social workers deal with.

I'm sort of mixing apples and oranges but it makes sense in my head :)
