Hmm, I don't know...These sound like good advices to do your job well and might even lead to happiness (which is good of course). But if your goal is to have a successful career maybe this would be more useful: Word hard on the right things, pay attention to what the others are doing and praise your own work uncritically :)

The question is: “what is your definition of success?” or “what is success to you? or “what do you think will make other people say you are successful?”

For a lot of uninspired and uncreative people, it’s mostly about the 3rd question, and it’s money, just money...

And they probably subscribe to a blog saying to blog everyday, and that’s how you get poor quality, uninspiring blog.

>>praise your own work uncritically

Am I not supposed to be critical of my work, and review it not pulling any punches, without being economical with the Truth?
