Greetings friend @samminator, certainly fear is the main enemy that our mind has, personally I have been afraid of many things but I have always taken that step forward to break with that fear and although sometimes the step is not too firm and I have stumbles and my fear increases I keep going forward until I can achieve my goal.

Truly our worst enemy is fear, because it takes over our mind and does not allow us to move forward, so it is important to risk and take that fundamental step in our lives.
