At some point, everything is going to go south. You can either accept that, or get to work.

-Mark Watney (The Martian)

I use this quote a lot with my students. When they are conducting projects, I tell them that they can either accept that they will fail if they do nothing or they can start getting to work. Once they solve one problem, they can get on to the next and the next. Before they know it, they would have completed something that they have never thought possible.

Despite this not being said by anyone real, i find it inspiring especially when I am faced with the toughest situation. No matter how impossible things may be, getting to working it out definitely beats sitting around doing nothing. If you haven't watched the movie, the movie basically sums it all up pretty well.
