That an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it but the second destroys your capacity to distinguish truth from error.
Ayn RandThe man without a purpose is a man who drifts at the mercy of random feelings or unidentified urges and is capable of any evil, because he is totally out of control of his own life. In order to be in control of your life, you have to have a purpose-a productive purpose.
Ayn Rand
