Discipline and stubbornness are probably the two that have carried me the furthest in life. Not as disciplined as I used to be, but...discipline kept me stepping up even when I didn't feel like it. Still a stubborn SOB though. Stubbornness to refuse to quit even when everything and everybody seems to be telling me to.
Self-awareness and patience can go on the "stack" as well. Knowing my limits. Knowing when to push on and when to rest. Knowing when I'm full of shit and need to course correct. Patience too. It is still a work in progress. Then again, they all are I guess. I'm impatient by nature.
Still working on all of it. Probably always will be.
