The increase in your value comes before the increase in your paycheck.

Pay follows worth, not the other way around. Before an employer or client will pay you more, you have to become someone who solves bigger problems, makes fewer mistakes, or brings skills that are harder to find. The raise is the visible, late result of a change that happened quietly and earlier. Waiting to be paid more before you invest in yourself is like waiting for harvest before planting.
