You need a "Pusher"- When doing it alone, it's too easy to quit. Surrounding yourself with others working toward a similar goal gives you motivation and support. Find someone that can be a little "Pushy" with you!
The Believers- Find people who are better than you, smarter than you... these people will lift you higher. Find people who believe in you more than you believe in yourself.
New ideas- I truly believe that when you are working within a community of like-minded people the results are astounding. Our divergent world views and lenses mean that we all approach the exact same problem in a different way.
We should all strive to use the power of our community everyday... We need one another to survive.
