Here is a terrific article from a guy named Phil Johnson about surrounding yourself with a team of people smarter than yourself. This is hard for the typical leader to do, but it probably is the biggest factor in taking you beyond where you are.
Here’s one of the things Phil says in the article:
“Look for people who have accomplished a goal, or solved a problem, that you personally aspired to achieve and couldn’t. Make them tell you how they did it. Put your own convictions and beliefs on the table. Ask them to convince you of something new or, better yet, to change your perspective. Find out their sources. What do they read? Who do they admire? Where do they look for inspiration? I like to see people making connections that would never cross my mind.”
