Fear is a biological imperative, an ancient block of code embedded deep into your operating system. And, you believe it's fear that keeps you from doing the work that needs to be done?
You are wrong.
The primary function of fear is to protect you from mortal danger; not from doing the work. What prevents you from doing work that matters is your anxiety. The internal narrative that howls, "You're not good enough!"
Anxiety is a villainous combatant. It can derail projects. Sabotage progress. And drown you with indecision. I allowed my anxiety to have agency over my success until I decided that I will dictate my level of success.
How did I do it? I found the holy grail -- you can't defeat anxiety. Nor can you outsmart it. Or outrun it. Your best hope is to learn how to dance with your anxiety. Listen, to the internal narrative and give it no fuel.
If you want to do the work, that needs to be done. If you want to solve interesting problems. If you want to lead well. Then you must accept your anxiety for what it is - you telling you, you can't do it. When you can accept those terms, that is the moment that shapes your destiny.
