"Without fear, there can be no courage." - Christopher Paolini
I don't know your story, but I know mine. I believe that I've done the hardest thing I'll ever have to do. I reached out to my father after what seemed like a lifetime of wondering. I don't know the hardest thing you'll have to do, but whatever it is, I hope it's terrifying. I hope that you are shaken to your core, and feel as though you've no way out. That will be the most courageous moment of your life, as long as you do it, and do it honestly.
Perhaps fear is simply misplaced trust in your ability to handle a certain situation. Fear can also be wisdom in the face of danger. I know that in the moment I've been the most fearful, that was also the moment that I was able to find more courage within myself than I ever thought possible. I hope that you are able to find that same courage within yourself. I don't know your situation, I don't know your fear, but I can tell you this; anything worth doing is worth doing afraid. If you have something you're sacred of doing, whether it's meeting your father for the first time, moving cities for a new job, or asking out that boy or girl that you like, just do it. Even if you have to do it afraid. If fear is misplaced trust, then put your trust in something else. The extent to which your assurance can be shaken is the extent to which your assurance is built upon the wrong thing.
The funny thing about doing "the hardest thing", for me at least, is that it really sets the bar for what won't scare you in the future. There are things I can do, conversations I can have now, that I would have never have been able to do before. Once you realize that you've conquered your biggest fear, everything else feels a lot less intimidating, because by nature of it being the hardest thing you've ever done, you only ever have to do it once.
Sometimes fear comes out of overthinking and putting too much pressure on ourselves, so be afraid, and be honest, and just do it. Be honest with that person you're scared to confront. Be honest with that new job you're taking. Most importantly, be honest with yourself. Everything good comes from honesty.
