"Look for a partner you'll try to impress daily, and one who will try to impress you." Over the last couple decades, I've noticed that the best, most enduring partnerships in business (and in life) are among people who are constantly growing together. If the person you choose to depend on is constantly striving to learn and improve, you too will push yourself to new levels of achievement, and neither of you will feel like you have settled for someone you eventually outgrow."
