the comfort zone's like anything:
 if you stay there too long,
 it's benefits will start to wane,
 and that's when things go wrong

 and so, you have step out, and
 explore the world around;
 for what you'll find's not limited
 to what's already found --

 it's good to be adventurous,
 for young and old alike;
 for nothing's more mature than when
 we are most
