There are two worlds you can exist in.
In one world, you have a lot to do! Managing family, friends, your money, your work, your day-to-day tasks, learning new things, etc. When someone asks how you are, you are B-U-S-Y.
In the other world, you get to do it. You have wonderful friends and family, smart colleagues working on hard problems, big ideas for what your future should look like. You drop the fear and stay curious.
I try to remember this when things get stressful.
