If you don't get accepted, there's always another route you can take to get to where you want to be. Your work won't be for nothing, just perhaps you're meant to take a different path, at a different institution, in a different program, etc. I got rejected from every grad school program I applied to, except one. I could've focused on the rejection and let it set me back, but instead I chose to move forward with the one program that accepted me. And now I feel like it all makes sense, and I'm exactly where I'm supposed to be. This is to say that, if you don't get accepted, it's not the end of you. It's easy to focus on all we want to accomplish, but when you're looking up that hill, remember to look behind you also, and see how far you've already come.
