Very true, in the end everyone has limited time and it's impossible to learn everything. However, I do personally like roadmaps/guides like this since, as a beginner, it's hard to figure out what you dont know. So being able to see a list of what's considered some of the most important/relevant topics is useful in that regard.

Still I totally agree that getting paralyzed is a big problem, it's way better to program something "the wrong/inefficient/bad way" rather than to program nothing. A big part of my learning and growth as a programmer has come from coding something terribly, realizing "hey, this kinda sucks, I bet there is a better way to do this.." and googling a bit until I learn a new/better method of doing X.
