Positive attitude, as well as happiness, as well as smile, is contagious.
What you do rather than what you say is more convincing.
Let the positive objects prime us in our life.
Picture the successful result with its process in our minds to build belief.
Don't magnify a one-time failure.
Instead of trying to improve the deficiency, focus on how to strengthen the strong points. (Ask the positive questions.)
We don't need to wait until things get worse to learn to appreciate.
Set goals.
Be a benefit finder and creator.
