Maybe try a different sunscreen. I've used both the Coppertone and Neutragena Dry Block on my face. I prefer the latter. It's a little less greasy and I don't have trouble with it getting into my eyes. You might also try a headband. That'll help keep some of the sweat of your face to begin with.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
