When you make a mistake, don't look back at it long. Take the reason of the thing into your mind, and then look forward. Mistakes are lessons of wisdom. The past cannot be changed. The future is yet in your power.
In my early life, and probably even today, it is not sufficiently understood that a child's education should include at least a rudimentary grasp of religion, sex, and money. Without a basic knowledge of these three primary facts in a normal human being's life --subjects which stir the emotions, create events and opportunities, and if they do not wholly decide must greatly influence an individual's personality --no human being's education can have a safe foundation.
