Future Self vs Past Self


On one hand, I understand that you shouldn’t look at your past self to validate how you want to be in your future self or looking at your past self for evidence of what your future self can do.

I struggle with this.

I continually want to look at different areas of my life as evidence that I have done hard things in the past, so I can do different hard things in the future.

How do I stop looking for evidence? Or is looking for evidence ok as long as it validates who I want my future self to be?
