Be suspicious of convention.
Take charge of your own thinking.
Rouse yourself from the daze of unexamined habit.
Popular perceptions, values, and ways of doing things are rarely the wisest. Many pervasive beliefs would not pass an appropriate test of rationality. Conventional thinking—its means and ends—is essentially uncreative and uninteresting. Its job is to preserve the status quo for overly self-defended individuals and institutions. emphasis added
On the other hand, there is no inherent virtue in new ideas. Judge ideas and opportunities on the basis of whether they are life-giving. Give your assent to that which promotes humaneness, justice, beneficial growth, kindness, possibility, and benefit to the human community.
Examine things as they appear to your own mind; objectively consider what is said by others, and then establish your own convictions.
Socially taught beliefs are frequently unreliable. So many of our beliefs have been acquired through accident and irresponsible or ignorant teaching. Many of these beliefs are so deeply ingrained that they are hidden from our own view. The commonplace sluggishness of the lives lived by the undisciplined is dangerously contagious, for we are often exposed to no alternative healthful way of living. Awaken and be vigilant. Take stock of your habits to preserve your higher standards.
Many people declare with all sincerity that they are committed to their own integrity while engaging in thoughtless or intemperate actions. They proceed willy-nilly, undercutting their otherwise well-intentioned efforts by failing to face themselves and to articulate a coherent personal moral code to which their future actions would conform. Don't listen to what people say. Watch what they do and evaluate the attendant consequences.
Just as we must clean, order, and maintain our homes to move forward with anything; we need to do the same with our minds. For not only do we risk inefficiency by failing to do so, we invite our soul's very corruption. A disorganized, foggy soul is dangerous, for it is vulnerable to the influence of better organized but unsavory influences.
Trust nothing and nobody but yourself. Be ceaselessly watchful over your beliefs and impulses.
