Were you perhaps financially secure enough not to have to fear anything? Or tenured (Bell Labs!) that unemployment wasn't actually a threat to you? YMMV.
I believe most people don't have discipline to endure less than and the discipline to really listen to what power asks of them. There is a lot of great advice for people to do well in a job, but they just... don't apply it.
These people are best to be ignored.
"Have no fear" doesn't apply to the article, at all. You might as well write "what I learned was to not stick legos up my nostril". Also good advice. Also not applicable.
It's fine if it doesn't work for everyone, it's annoying if it isn't relevant to anyone.
A personal anecdote would be saying this is what worked for me. Not this is how you should do it.
It comes off as telling you what your problem is and how you should fix it.
I'm not sure your average adult would find "don't be afraid" to be "advice", or some deeply meaningful advice that only a cynic would think was anything less than excellent.
