You can't grow walking into what you already know.
Being vulnerable can be powerful, but it means walking into uncertainty with the faith that you will find what you need to grow forward despite what you find.
That said, know that the quality of your life is in direct proportion to the amount of uncertainty you can be comfortable with.
No matter what skills you possess or strategies you learn; regardless of the money you have or the people you know, if you doubt yourself; if you feel unworthy, or like you're not enough, then your fight is bigger than you could ever imagine.
But through your vulnerability, your victory is closer that you would ever believe.
