If you change the way you perceive yourself, who and what you are will change.
What you are is a fluid creation. You are not a solid, stationary thing. You are an ever-changing expression.
If you can begin to see yourself as an ever-changing expression, then the fluidity that is your true nature will return.
Part of our problem as humans is that we try to lock in what we are, to define and solidify who and what we are. And so our faults and weaknesses and mistakes are set in place and used to define us.
You are a brand new creation in every moment. As you read these words, you are brand new.
Enlightenment is feeling the brand-new-ness of the present moment.
