When you become moderately successful at something, there are two ways to describe your success:
It’s just easy to do.
It’s difficult, but I’m pretty good at it.
In the “it’s just easy” camp, you set yourself up for a situation where you’re expected to do well, so success is just status quo. But if anything goes wrong, you’ve failed to clear the lowest possible bar.
In the “it’s difficult” camp, you set yourself up to feel proud of your achievements, while also protecting yourself from becoming demoralized in the face of failure.
Easy commoditizes success. Difficult makes you valuable, while leaving room for continual improvement.
