Music and guitar performance is an academic subject like any other, and has a standard curriculum. There are a few well known top schools, Berklee, MI etc. There are a couple of standard method books.

There really is no need to try to discover "how to get good at guitar" any more than you need to discover how to get good at mathematics.

Music is a language, you practice reading, writing, listening and playing (speaking).

How to get the time for the study, is the challenge, of which there's no "secret solution". Only people who are relatively well off can afford these schools, and/or take the risk of studying something so frivolous with such a low chance of paying off.

If you practice something diligently for 30min every day, it will still take you something like 25 years to rack up the hours of a 4 year masters degree.

The book "When Less is More: Visualizing Basic Inequalities" by Claudi Alsina might also be of interest.

In a team of 10, you have 10 x (10 - 1) / 2 = 45 communication channels

In a team of 15, you have 15 x (15 - 1) / 2 = 105 communication channels

Which implies that the time you need to spend communicating would be around double. So if you need 1 hour meeting per day in a 10 person team, you will need 2 hours of meetings in a 15 person team.

The only solution that I know, however impopular, is to form a hierarchy of information, just like you would organize a growing code base in a hierarchy of abstractions.

I have also experienced a lower quality in these books, but I'm hoping that it will enable some customization options such as paper size and binding.
