If you are high in trait openness and creative, creativity itself will provide a powerful buffer against fear provided you give yourself authentically to your work/play enough. But even those who don't consider themselves creative have some kind of focused activity they may be putting off. Authentically expressing something or doing something you feel dutiful to do in in spite of the fear gives a great sense of satisfaction and quells the part of you that feels downtrodden by circumstance, activating a sense of agency. What the japanese called Ikigai (生き甲斐, "a reason for being") is a Japanese concept referring to having a direction or purpose in life, providing a sense of fulfillment and towards which they the person may take actions, giving them satisfaction and a sense of meaning.[1]
Procrastinating is physically stressful on the body, so one way to behaviorally normalize making bold actions is to break the beginning of the task into something small and easily manageable and write it down. Effectively practicing doing the thing you know to be both difficult and worthwhile in tiny bursts allows you to build the muscle of facing fear as a practice. I.e draw or write or work out 1 minute a day, but allow yourself a higher limit of how much you can do in a day. Once you've done the minute you'll usually feel like continuing because the fear itself is what feels bad and usually if you're doing an activity you're supposed to be doing you will want to continue after starting.
A few things that diminish fear: Making art, being vulnerable with people you trust, journaling your thoughts, winning against others in competition, expressing yourself authentically, Qi Gong, Trauma Release Exericise (TRE), physical touch and intimacy, meditation, heart rate variability training. Threats don't feel threatening when your autonomic nervous system is in balance. You can use a simple mental tool to think of something you appreciate in order to shield yourself from the effects of fear. Cultivating a general state of gratitude/appreciation appropriate to your life is a powerful shield against fear. Or at least sitting down for 2 minutes and practicing it with intention. Ultimately you can't get rid of fear altogether completely as it is a behavioural indicator and not just a symptom, but you can protect yourself from an inappropriately stressful experience of it in many different waysOne last quote from terence mckenna...
