The only people who don't have problems are in a cemetery.
You will soon break the bow if you keep it always stretched.
Don't bother. The glass is half-empty.
Nothing can stand in the way of the man who focuses his entire self on a problem.
Watch your manner of speech if you wish to develop a peaceful state of mind.
Every day remind yourself of your own ability, of your good mind and affirm that you can make something really good out of your life.
