Fear is almost always going to make a guest appearance now and then in your life. When you make a big change, start a new piece, finish an old piece, or put your work and yourself out into the world, in general.
What matters isn’t tamping down the emotion. It’s primal, and with us since long before we became mammals, even. The feeling comes, and it’s okay to feel it. But do more: embrace it, examine it, see what it does to you physically.
After that, you can more easily push it aside and do the thing you have to do. Denying it or avoiding it only turns it into something monstrous at the edge of your sight. But, it’s just fear, one emotion among many.
Fear can help us get moving or keep working. You can use the energy—the thrill, even—that rises up in it to your advantage and your work’s benefit. You don’t have to shove it aside, you can make it your ally. If it’s going to be there anyway—and it is, you’re only human—better to embrace it fully than try to ignore it. Like pre-performance stage jitters, a little nervous energy imbues your work with oomph.
Trying to run from fear is pointless—it’s attached to us like a kick-me sign taped to our backs. Try to get away from it and it flaps away with every step. Calmly reach around and accept it and you might be able to pull it off.
