This post from Michael Hyatt, Two Types of Thinkers: Which Are You? really a good. I would like to share with you all here. The two types of thinkers are abundance thinker and scarcity thinker. I really like those terms. Michael explained each type with 8 characteristics:

Abundance Thinker:

1. They believe there is always more where that came from.
2. They are happy to share their knowledge, contacts, and compassion with others.
3. They default to trust and build rapport easily.
4. They welcome competition, believing it makes the pie bigger and them better.
5. They ask themselves, How can I give more than is expected?
6. They are optimistic about the future, believing the best is yet to come.
7. They think big, embracing risk.
8. They are thankful and confident.

Scarcity Thinker:

1. They believe there will never be enough.
2. They are stingy with their knowledge, contacts, and compassion.
3. They default to suspicion and find it difficult to build rapport.
4. They resent competition, believing it makes the pie smaller and them weaker.
5. They ask themselves, How can I get by with less than is expected?
6. They are pessimistic about the future, believing that tough times are ahead.
7. They think small, avoiding risk.
8. They are entitled and fearful.
