The following quote by Dee Hock, founder and CEO emeritus at Visa, is spot-on for anyone seeking to become a great leader:
Control is not leadership; management is not leadership; leadership is leadership. If you seek to lead, invest at least 50% of your time in leading yourself—your own purpose, ethics, principles, motivation, conduct. Invest at least 20% leading those with authority over you and 15% leading your peers.
When it comes to your career and your ability to become a great leader, the word ‘invest’ is perceptive. Invest in yourself; after all, you –your skills, talent, abilities, etc. — are the most valuable asset you own. Start with yourself.

The Product Management Perspective: Dee Hock’s quote nicely defines the product management perspective. Find ways to invest in yourself; everyone around you will benefit.

Yes, couldn’t agree more, I think that personal investment is absolutely critical. As part of my quarterly performance reviews with my employees I insist that they build both their product road maps and their own personal roadmaps. Nice quote!

— And the remaining 15% is vacation? 🙂
