Scrolling feels good for a second. Finishing something hard feels good for a week.

Pleasure has different half lives. Some of it is spent in the moment and leaves nothing behind, and some of it keeps paying out for days because you remember what you did. Neither is wrong, but they are easy to confuse when you are tired and reaching for the nearest thing. The cheap one is always closer to hand.

Notice how you feel an hour afterward rather than during. Try putting the difficult thing before the easy one this week and see what the evening is like. Rest still matters, and the best rest tends to follow something finished.
