I'm always thinking about "Create vs. Consume" => make sure it's at least 50-50, aim for 80-20. Most men I've met on death beds regretted doing nothing.
Do I truly understand a problem space or am I just making a water-cooler level of abstraction? Dig deep, down the bolts, or shut up.
Are the kids happy? is the wife happy? Then I'm happy. People remember you by how you made them feel.
And this last one is controversial, even within me: prayers are not lost to the woods.
