You have the freedom to choose to be optimistic or pessimistic. You can peel off your old attitude like a suit of clothes, and put on a brand spanking new attitude every single day. It's as simple as that.
You have to talk about what you love, to bring what you love to you.
People who have great lives think and talk about what they love more than what they don't love. And people who are struggling, think and talk about what they don't love more than what they do love.
Every day, in every moment, you make the choice whether to love and harness the positive force - or not.
