Every time you hit a goal and instantly move it, you rob yourself of the moment you worked for.

Moving the target the instant you reach it means you never quite arrive anywhere. The satisfaction you were working toward gets deferred permanently, which trains you to associate achievement with nothing in particular. Over time the striving stops connecting to any feeling at all, and you continue out of momentum rather than desire.

When you hit the next one, stop for a day before setting anything new. Tell someone. Do something that marks it, however small. The pause is not laziness but the way effort gets attached to a result, which is what makes the next effort possible.
