After meeting with some success, it is often difficult for a leader to maintain a high level of passion.
I think it is important not to get into a personal comfort zone. To avoid this, I try to constantly take on new challenges, to test limits, and, often, to discover that those limits were never really there.
No matter how successful you believe yourself to be, you can never feel as if you’ve reached the absolute pinnacle.
