Every single person I know just wastes their time with that. Usualy they work long hours and still don't get much done.
But hey, they have Zettelkasten with things the never read. A to do list with stuff they never do. And they go out in the morning at 5 for jogging, while gulping down a liter of coffe or energy drinks which results in them being groggy the whole day.
If you ever think you need to adhere to what is preached in any self improvement thing, just don't.
Habe your shit in order, avoid working mor than 7 hours day and take your weekends and vacations seriously.
Especially in IT nothing will get you further than being smartly lazy.
