If your not failing your not getting better.
Success lives on the other side of failure.
This is just an unavoidable fact.
If you aren't willing to push yourself farther and be willing to fail, you will not get better.
You will actually regress and get worse.
Think about snowboarding.
You get better by pushing yourself with sharper turns and steeper hills.
This goes for anything:
“If you aren’t pushing you aren't getting better”
Knock on the door of terror and progress towards greatness.
