Don’t follow any advice, no matter how good, until you feel as deeply in your spirit as you think in your mind that the counsel is wise.

The line urges skepticism toward even well-intended guidance and emphasizes personal discernment. Rivers frames “good advice” as insufficient on its own: counsel should be tested not only by rational evaluation (“think in your mind”) but also by an inner sense of alignment (“feel…in your spirit”). The quote reflects a practical ethic of self-trust—use others’ experience as input, not as a substitute for judgment—while also warning against the social pressure to comply with authoritative voices. Its significance lies in balancing intellect and intuition: wisdom is portrayed as something one must internalize before acting, rather than merely accept.
