Don't fear the unknown. Walking through the unknown will show you to yourself. It will show you where you are strong and where you need help. It will show you how to ask for help. It will show you where you must have faith in yourself, faith in others, and faith in the road you've chosen. But all you fear is that lack of knowledge, and the only way to know the road is to walk the road. Don't fear the untrod path, whether it's one you missed or one you hope to take one day. All paths are leading you precisely where you need to go. Yes, you can choose the rocky side path rather than the scenic high road. Yes, that path might trip you with unseen branches and fling you into the mud. Another path might take you the long way, through the fields and past a desolate lake. But you will always get where you've chosen to go. It may take so long that you forgot where you were aiming. It might take far less time than you dreamed was possible. But you will get there. Just keep walking.
Don't fear change. Change signifies growth. Change signifies a tearing down for a more stable rebuild. Change is at the very heart of the human experience and it pumps the blood that keeps it healthy. Don't fear the things you can't see, don't fear the untapped future or the pained past.
Expand yourself to hold all of it - the fear, the unknown, the future, the past, the trust, the long winding road, and those who will help you along the way. You are greater than you can know, and you can hold everything that has or will come. Embrace what's coming now. And know that you can hold it, for you can hold the world.
