"I should save more" is a fine intention and a nearly useless plan. It has no number, no deadline, and no way to tell whether you're on track — which makes it very easy to quietly stop doing.

"Save $2,400 for a trip in eight months" is a different kind of statement. It has a target, a timeline, and a monthly number that falls out of simple division — $300 a month. That specificity is what turns a vague intention into something you can actually check yourself against.

Why specific goals hold up better

A specific goal gives you a clear signal when you're behind — if a bucket meant to hit $2,400 in eight months only has $900 in month five, that's immediately visible, and you can adjust. A vague goal never gives you that signal, because there's no target to fall behind on.

Turning "someday" into a number

The exercise is simple even when the goal is fuzzy at first: put a rough dollar amount and a rough timeline on it, even if both are estimates you'll revise later. A goal you can always sharpen later is far more useful than a goal that's never been given a number at all.
