Riffs:

Why complain? If you complain three quarters of the people you complain to don't really care, and the rest are happy you have a problem.

It doesn't matter if you fall down 7 times; just get up 8 times.

A person who says it cannot be done should not interrupt the person doing it!

Be a cheese mover (don't worry about who moved it; move it yourself.) But if you move my cheese I'll kick your ass.

Finally there are no sure things; there is no security; there are only opportunities.
