Shift your focus from how hard you work to how much you produce. The amount of input doesn’t matter if it’s inefficient and wasteful. Output is the only currency. If there’s no output then all the input in the world doesn’t make any difference. 

If you’re huffing and puffing, and telling anyone who’ll listen how hard you work, or how burned out you are, then you’re probably doing it wrong.

Pause and recalibrate. There’s infinitely more joy and energy in serving others through results.
