I think it's a subtle but important one actually, the dopamine rush is a bit a self pleasuring quest, so thinking for others is already a step in the right direction

That's also an idea I keep having about general adult life, career and happiness. Youth is all about intense self satisfaction, but running this race too long is a dead end, and it should be hinted that working for other citizen is actually a good thing for you (because it avoids this dead end)
