I think this is more true of the two. Purposeful work is important to feeling fulfilled. Work that isn't appreciated isn't likely to leave one feeling like they have a purpose at work outside of generating a paycheck. I think the other point is probably less wise. There will almost always be comparisons in which one falls short in terms of salary, even up to the billionaire class level. For me personally using that as a gauge is a recipe for constant unhappiness.
