People who have attained things worth having in this world have worked while others have idled, have persevered while others gave up in despair, and have practiced early in life the valuable habits of self-denial, industry, and singleness of purpose. As a result, they enjoy in later life the success often erroneously attributed to good luck.
Good humor is a tonic for mind and body. It is the best antidote for anxiety and depression. It is a business asset. It attracts and keeps friends. It lightens human burdens. It is the direct route to serenity and contentment.
