Things I must remember

Yesterday is but a dream, tomorrow but a vision. But today well lived makes every yesterday a dream of happiness, and every tomorrow a vision of hope. Look well, therefore, to this day. - Sanskrit Proverb

Work like you don't need money, love like you've never been hurt, dance like no one's watching, learn like you'll to live forever, and live like you'll die tomorrow.

And the biggie:
Don't take life too seriously. You'll never get out of it alive. - Elbert Hubbard
