The 3 types of Dangerous People

Micheal Maddock writes about 3 types of people to fire immediately. This applies beyond the world of entrepreneurs and work teams. It applies in all of life.
- Victims – they want the problems.
- Critics – they won’t and they don’t want you to either.
- Know-it-Alls – they refuse to learn.
If you want to improve quality of life, stay away from people that reduce your joy.
Question: In the case that it is impossible to get away from someone of type 1, 2 or 3 do you have any ideas for antidotes?
What are your thoughts?
