With every accomplishment there is a desire to take the next step. With every success there is the desire to be more successful next time. We road trip out to Wyoming to climb a tower, and even on the drive home I already wonder, 'how do I top this?' I finish a huge project with significant technical hurdles and I wonder, 'how do I top this?' It is like a race of attrition. There is no finish line unless one stops. There are no limits unless one creates them.
