Toxic People

Toxic people create unnecessary complexity, strife, and, worst of all, stress.

People inspire you, or they drain you; pick them wisely.

Negative and toxic people are energy vampires. Keep your energy and psychological resources for things that advance your life rather than drag you down.

You can avoid all this by setting limits and distancing yourself when possible. Think of it this way: if the negative person was smoking instead, would you sit there inhaling the secondhand smoke. Secondhand smoke is the combination of smoke that comes from a cigarette and smoke breathed out by a smoker. When a non-smoker is around someone smoking, they breathe in secondhand smoke. 

Exactly. The best way to deal with negative people is to not deal with them at all. Set limits. Distance yourself from them completely.
