As every thought and idea comes to you, examine it closely. If you can, see what it really is and what qualities it has. Think it through carefully.
As every fancy and imagination presents itself unto thee, consider (if it be possible) the true nature, and the proper qualities of it, and reason with thyself about it.
When you find it hard to get up and wake from sleep, remind yourself of this: doing things for the common good is what your nature requires. It's what human nature requires. But sleeping? Even dumb animals do that. What could be more natural and satisfying than acting according to your true nature?
When thou art hard to be stirred up and awaked out of thy sleep, admonish thyself and call to mind, that, to perform actions tending to the common good is that which thine own proper constitution, and that which the nature of man do require. But to sleep, is common to unreasonable creatures also. And what more proper and natural, yea what more kind and pleasing, than that which is according to nature?
