[disambiguation]

Reminds me of a quote I saw recently:

“It has gradually become clear to me what every great philosophy up till now has consisted of – namely, the confession of its originator, and a species of involuntary and unconscious autobiography; and moreover that the moral (or immoral) purpose in every philosophy has constituted the true vital germ out of which the entire plant has always grown.”

I think "philosophy" can be replaced with "advice" and it still applies.
