“You’re better off doing this.” “But you do the exact opposite!”
Sometimes I give out advice that contradicts my own actions. But just because I don’t follow my own advice doesn’t mean it’s bad. Quite the contrary, it can be an indicator that I actually know what I’m talking about! After making a mistake, I learn from it and try to not do it again. I may fall a second time, even though I knew better. That’s just how things are, mistakes happen.
Besides, sometimes it can be more difficult doing the right thing. I can tell my sister to work hard all I want (and I know she will), but a “but you don’t” reply is inevitable. Yes, I’m not following the advice I hand out, but that’s just because it’s not always the easiest to do. I can see the right path, but I may not be able to walk it.
Long story short, you shouldn’t rate advice quality on the actions of the advisor.
