Yes. The money. More money and potential millions.

But as @honeydue said it

or maybe it's.just that you're used to it, to doing something you don't like and so choose to subject yourself again and again to that thing, despite not liking it. It's the status quo and most folks don't want to upset the status quo in their lives :)

The fear of unknown if one leaves. The agony of doing things again and working for it to find something that might be better, but might also be awful. Who knows.

Is it so that if there are no big problems in ones life, one must always find something to complain about? First world problems. Or is it the fact that if someone's really stressed out, they complain about everything? Sees, hears of thinks no positive things. Or it is it that out of all the posts here, sometimes almost all of it seems to be negative stuff or one just stumbles upon complains because of personal (sub)conscious choices? A click here, a click there.

Complaining, an inexhaustible natural resource. If one could just stuff it into batteries and cool the whole town next summer when the next heatwave comes.
