“ If you can't run, you crawl. If you can't crawl-- you find someone to carry you. ”
Even if you are on the right track, you'll get run over if you just sit there.
If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward.
If you think you are too small to make a difference, try sleeping with a mosquito.
If you don't give up on something you truly believe in, you will find a way.
I alone cannot change the world, but I can cast a stone across the waters to create many ripples.
