While this advice is mostly true you can't split it up in days. You have to do most of this at once from the start.
I have been doing something similar to the advice in this article and it's been working for me. I took a small hobby blog and got more serious about it, implementing these ideas as I go. So far it's going well, and while I think you can do a lot of things things at once I don't think you need to feel pressured to get it done all in one go.
