Work smarter, not harder.
Do more with less.
Short pithy sayings are always good for a moment's pause. Most of them have at least some element of truth to them. They sound good, are mostly logical, and hey, maybe even worth a shot.
Then Seth Godin comes along and messes with my brain big-time:
If trying harder isn't working because you're already trying as hard as you can, maybe it's time to try different.
If it's not working, harder might not be the answer.
What do you need to try different today?
