We are human after all, but when you feel like this, do you even like yourself?
I do not.
On one of those days I over pep myself up to be positive.
I make it a point to smile gloriously and say a very friendly "hello" to the next person I see, maybe ask how their day is ~ let them know I think it is an awesome day.
After I do this with about 2 people, I am seriously in a positive and upbeat mood myself. What a salesman I am!
So, once again as my mother, and probably your mother used to say, "turn that frown upside down". She was right ~ It works!
Make everything fun and keep your positive eyes and ears open. Close those negative Nellies.
