Dread is expensive in ways that never appear on a payslip. It shortens how long you last somewhere. It makes you avoid the one person you ought to be talking to. It eats whole evenings that get spent recovering rather than living.
Joy runs the other way, and its effect on money is mostly unromantic and mechanical. People who don't dread their days stay longer, say yes more often, and are easier to be around — and a surprising proportion of work arrives through somebody who found you easy to be around.
None of it is instant. But the direction is real, and the evenings are yours either way.
