The only thing you can do it take it piece by piece, day by day.
I could try and plan and figure and prepare so everything works out just great, but I know its likely to change within a day or two... after another thoughtful conversation... following another internship.

So I'm not quite sure why I spend so much time focused on the future and obsessed with having a functional plan when I know that my plans so frequently change. I suppose it just makes me feel better.
