i too strive in such a situation, but it still makes a difference whether the work is meaningful or not. especially when you get to sleepless nights. it makes difference if that customer is a hospital or some other meaningful industry, or it is something meaningless like an online game, other entertainment or worse, gambling. i wouldn't work overtime for the latter (unless the pay is worth it or the team is good)

i can definitely confirm that meaningless work is more boring.

So it is essentially all about money, and meaningfulness of the job is just another bonus, along with medical insurance, prolonged vacation period and anything else that might make you choose less paying job.

That said, I can imagine people taking pride and joy in building an online game and making sure it works reliable even as audience grows way past anticipated level.
