I think that 5. and 10. are not as good advice as they sound. Not many people are good teachers and if you try to learn with other, they will oftentimes attempt to do all the work, especially thinking part, for you. If they already know more, there is no way for you to match their speed and you end up just doing what they dictate - worst possible way to learn. If you want to become good, you need to spend time learning alone, when you can try out wrong path for a few minutes, solve problems independently even if it is slower, make mistakes and finding out by yourself.
It is different if people around you have good social skills on top of tech skills, but many people are not like that. A contact with community is important for motivation and having possibility to work with good quality people is indispensable. However, much of important learning happens when they are not in the room and they can not take control of keyboard and tell you solutions to problems before you had the chance to think.
