Love this twist. For me, of the three, personal integrity is the biggest. I believe success naturally follows from integrity.

Even if you set aside the philosophical and theological implications, your body "remembers" - someone that doesn't have integrity is likely to deep down have low self-esteem which reduces his ambition and passion in life. Which inturn reduces the chances of success.

It's the same with business. When you have your own principles and priorities, other things will naturally wait.
