You're not very similar in the ways that you each meet the world, but your differences are complementary. And if you can learn to appreciate them as such, you could really have a dynamic and mutually satisfying friendship. Each of you will bring a unique gift to the relationship that will help you both to achieve the goals you've set for yourself.
You're the idea person -- the energetic initiator who's not afraid to take risks, get competitive or get out there to get something done. Your buddy is more into making calculated moves that will ensure every venture is a success. So why not blend the two styles? Your energy and optimism will help to boost your friend's spirits. If you can appreciate your differences, which should be easy, you'll make a great, dynamic team.
