I'm doing a run for cancer research and I need something to write on my shirt...?

Doing a run this weekend for cancer research. One of the people I work with was recently diagnosed with cancer. She's the type of person who'd do anything for you and is always there and ALWAYS works too hard. We all had shirts made for her but there is a big blank spot in the middle front and we're supposed to write SOMETHING in there. I don't know what to write! Should it be funny? Should it be inspirational? Should it be vague or specific? I'm at a complete loss. This lady, I've recently gotten close to her and I love her to death but I don't want to mess up the shirt by writing something stupid on there :( Please, please help!
