I don’t know whether “Manage your day-to-day” is a best-of of the relevant articles on 99u but it certainly could be. So here is a small collection of articles by various authors on three productivity topics: finding focus, the use of tools, become productively creative.
If you have ever read a productivity blog there will be nothing new. Still, the little book was rather entertaining and a very quick read. Most of the advice is or should be common sense. Nevertheless, I had the feeling that there are also some inconsistencies. Of course, if you have several authors independently writing up some material on related topics and they start talking about their own personal experiences and try to come up with some general advice based on these they will contradict each other in some points. There is no one-size-fits all.
