This site has changed visually over the years, but the tagline has not because it reminds me of a critical life lesson... 

"Playing" - We are actors. We choose who we want to be and act accordingly. If we feel "small", it's not because the world is big; it's because that's the role we've selected. We can always choose a different path. Plus, life is fun! We should always be playing!

"Serve the world" - We must leave this planet better than we found it. That includes our environment, our communities, our families, and ourselves!

Here's my original inspiration:

“Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure... Your playing small does not serve the world. There is nothing enlightened about shrinking so that other people won't feel insecure around you... as we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others.”
