Don't ever admit that the world has not given you an opportunity
If your environment is not to your liking, change it!
Your big opportunity may be right where you are now.
Every problem comes with an equal or greater opportunity
Success attracts success and failure attracts failure because of the law of harmonious attraction.
A man is most efficient and will more quickly and easily succeed when engaged in work that he loves, or work that he performs in behalf of some person whom he loves.
