"I give myself very good advice, but I very seldom follow it" is a humorous quote from Lewis Carroll's "Alice's Adventures in Wonderland" and "Through the Looking-Glass." It reflects the human tendency to advise others wisely while struggling to follow the same advice oneself, highlighting the gap between knowing what is right and actually doing it.

This quote captures a common humorous paradox and showcases Carroll's playful use of language and insight into human nature. It suggests that even when one has good intentions or knows the right course of action, it can be difficult to implement that advice in practice.
