I am a huge advocate of optimism, positive thoughts and the like. I have learned through experience that if you think negatively, negative things will come your way. Have you ever had to sever ties with someone because they were so negative that it was bringing you down as well? Sometimes you have to go through this exercise, but in the end you feel like a weight is lifted from your shoulder and you can breathe a bit better.
People have commented to me that I am always so positive, and now you know why! I feel that if you surround yourself with authentic, optimistic and confident people you can not go wrong.
