I am still reading Robert Greene's book The 48 Laws of Power and I was right in the middle of allowing myself be controlled by my emotions when I came across law # 10. It talks about the "infectious" emotional states of others - how others, with their problems and instability can bring us down. While I don't consider myself unstable, it caused me to reflect that we sometimes spend to much time with people that, instead of pushing us forward, pull is down. When we don't get our work done or accomplish our goals because we spend to much time with them, we may need to reflect and reduce the time we give them. Sadly - we often really like these people. Maybe we have known them for a long time. But we need to be cautious of the influence they have on our effectiveness  and impact in this world.
