Yes, it's emotional to disregard advice you know is good. However it is a logical reaction to have.
It is logical for humans not to trust or accept advice from a hypocrite, even if that advice may be good. It's not about the advice itself, but about who gives it. That was my point.
Unfortunately humans have emotions, and those emotions factor into our so called "logical decisions". To ignore our emotions is to pretend we are machines, and machines wouldn't be in these situations, as a machine wouldn't give advice it doesn't follow itself.
Now, if we were machines, sure, if the advice is good, it's good, doesn't matter who gives it.
Furthermore, if I already know the advice is good, did I receive advice?
That's why I host all my shitty unfinished projects in a Gitea instance in my VPS. Now they actively cost me money and I feel (a tiny bit) more incentivized to do so something with them!
