If you set the bar too low, it’s not worth doing.
If you set the bar too high, it’s unrealistic.
If you set the bar comfortably where people know they can do it, it becomes a mundane chore.
If you set the bar uncomfortably high where people believe they can do it with some hard work and faith, then it becomes an invigorating challenge.
This is the sweet spot to target for yourself and others.
Bonus: The more you stretch, the better you become.
