Ferris Bueller Quote | Photographic Print - This place has some really cool T-shirts you can buy, such as this Feriis Bueller one. They also have PIXAR ones, Breakfast Club, and other movies. This could also be a cool quote to print out for your wall.
I love this. He doesn't just think positive and assume nothing will go wrong ever then freak out when it does. He doesn't ignore problems. He knows things will go wrong and he knows he will do everything in his power to figure out the next step, then the next until it works out.
