Diligence - Diligent developers take ownership of their work without being possessive. Diligent programmers fix broken windows.
Humility - Humble developers take pride in their code, but don’t snub constructive criticism. Humble developers know they can always improve themselves.
Patience - Patient developers remain calm during times of stress, and don't surrender to the temptations of a quick fix. Patient developers have the endurance to carry a product across the finish line.
Liberality - Broad-minded developers base their decisions on proofs and particulars instead of preconceptions and prejudices. Broad-minded developers listen to the other side and attempt understanding.
Creativeness - Creative developers find a way around the brick wall in front of them, and do so without creating a mess. Creative developers find the elegant solution to a difficult problem.
Adaptability - Adaptable developers have the ability and willingness to learn new skills and accept new responsibilities. Adaptable developers continue to grow.
Resilience - Resilient developers bounce back from boneheaded bugs and bursting dotcom bubbles to code again another day. Resilient developers appreciate failure as the upward slope of the learning curve.

I still have to work on 6 or 7 of these.
