Do it!

the sooner you make an attempt despite the fear the sooner you can make an additional attempt. as you put off your initial attempt, you are putting off the entire series that would then constitute the very practice which is required to develop skill so that you no longer fear it

If you want to understand who you are or could become, it is helpful to learn more things and be active: improve your craft, put yourself in new situations, push yourself. How else are you going to have a sample of reactions to study?

You prefer to cling on to your potential as a pristine hypothetical, that's why you never let yourself try

Courage is not the absence of fear, but rather taking action despite the fear.
