1. Gotta laugh
2. C'est la vie!
3. Don't tell people how great you are - show them and let them tell you (a great piece of advice I overheard my dance teacher telling her son who was telling me how great he was at somersaults at age 4).
4. I am only one, but still I am one. I cannot do everything, but still I can do something; and because I cannot do everything, I will not refuse to do something that I can do. - attributed to Edward Everett Hale and Helen Keller...not sure who actually said it first!
5. When in doubt, just say "perhaps." (This is my favorite thing to say when I am asked to commit to anything - no is too harsh; yes commits me when I may not feel like it; perhaps is just the perfect combination of positive, yet vague.
6. Well, honey, everyone has a different size cup. - my Moomala, when referring to how much stress each of us can handle on any given day.
