Remembering that you are going to die is the best way to stop being afraid of everything. What exactly are you protecting? The opinion of people who will also die? The comfort of a life that is already slipping by? You came in with nothing and you are leaving with nothing. You are already naked. So there is genuinely no reason not to follow your heart, say the thing, take the shot, build the life you actually want. Death is not the scary part. Wasting the time between now and then is.
