Courage is resistance to fear, mastery of fear, not absence of fear.

Fear is not the opposite of bravery; it is the raw material. Someone who feels nothing risks nothing, because nothing is at stake for them. What you are after is not a quieter heart but steadier hands while the heart races. Courage is the decision you make while the fear is still running.

Stop waiting to feel ready, since the feeling is not a reliable signal about whether the thing is worth doing. Pick one thing you have postponed because of how it makes you feel, and do the smallest real version of it today. Notice that the fear stays and you move anyway.
