"You Can and WIll"

Do your best; take it as it comes. 
You can handle anything if you think you can. 
Just keep your cool and your sense of humor.
    ~Smiley Blanton, M.D. (1882-1966) American Psychiatrist

One of my father's sayings was: "You can and you will". 

This taught me that to make changes and obtain ones' goals: Attitude is Everything!

The best teaching tool of this concept can be found by reading, (again), Oh, The Places You Will Go,  by Dr. Seuss.
