HEALTH PROBLEMS: Beyond the obvious disruptions illness provoke, medical attention costs so much that even modest treatment can oblige us to work a very long time at jobs we may not enjoy that much just to pay the bills. Therefore, take care of your body.

PSYCHOLOGICAL PROBLEMS: If one is hung up, for example, on blaming others for a bad situation, or is too depressed to work for changes in life, or can't think clearly for one reason or another, then the mind finds it harder to think pleasing thoughts. Therefore, do what you must to clear your mind.

ADDICTIONS: Addictions keep us from enjoying life if only because they cost so much, causing us to have to work long hours to pay for them. Addictions also inevitably affect our health and cloud our minds. Therefore, overcome your addictions.

BEING TOO SUGGESTIBLE: Our consumption-oriented society constantly urges us to buy new things that we don't really need. Friends and family require us to live in ways in which we don't believe. Our conservative religious and political institutions demand that we behave in ways appropriate for earlier times, not ours. Therefore, to get the most out of being a student of nature you must think for yourself, and do as you truly believe.
