A habit is like a mental roadblock; it stops the expansion and growth of mind; it is something that is always with you and demands physical and mental attention, and sometimes to the almost complete exclusion of the other things of a constructive nature. –Alfred J. Parker

When viewing or thinking a thought, always clarify it for the value of its logic and reason; divest it of imagination, mystery, and all falseness; see the clear intent, whether constructive or otherwise, and never compromise with illogicality; a statement is, or is not. See it for what it really is, and do not attempt to clothe it with personality; this is what so often leads to jumping to conclusions and self-pity. –Alfred J. Parker

Know that a wise man changes his mind; but a fool never. Be humble, and thus keep the door to wisdom always open. Ego is the greatest destroyer of potential thinkers. Be principled, just, and honest at all times; and peace, health, and success will follow you all the days of your life. –Alfred J. Parker

The doctors of the future will give no medicine but will interest patients in the care of the human frame, in diet, and in the cause and prevention of disease. –Thomas A. Edison
