Nature cannot be tricked or cheated. She will give up to you the object of your struggles only after you have paid her price.

Patience, persistence and perspiration make an unbeatable combination for success.

Success in its highest and noblest form calls for peace of mind and enjoyment and happiness which come only to the man who has found the work that he likes best.
