Optimism is contagious, conversely, so is negativity.
Don’t believe me? Try it. When you go to work tomorrow, or with a crown of people. Try saying something positive, praise someone or something, Share a positive story or how you have been blessed lately or thankful for something. Another day, complain about the weather or something wrong/negative that happened to you. Then sit back and see what happens.
The Law Of Attraction is a real thing. Try focusing on the good & see how it may return. Bless someone & see how you may be blessed. Count more things that you are thankful for, vs things you are not.
Optimism & Positively is contagious, so go out & catch that bug.
Blessings & Peace.
