Programmers are introvert. We live in our own world of logical patterns. Everything to us must have a reason. We are always solving problems. Solving a puzzle is more important than communication on conversations. The experience is very close to a yogi that just lives in own realization. Programmers can become great teachers of meditation. Business people are extroverts because they have to interact with partners and customers. The best combination is found when synergy is created between two or more partners. It is very important to understand each others strengths and weaknesses. Stay quiet and be more focused.
