No matter how optimistic you are by nature, if you spend a lot of time around
negative people or situations it will have an effect on you. Even you, Leo,
could be adversely affected if you spend too much time in a dark environment.
You are someone who has a very strong mind, and you believe in the power of
positive thinking. Don't fool yourself into thinking you can avoid being
pulled over to the "dark side" by someone who is a pessimist. Spend your time
gravitating to the light.
