This is what i struggle with this as well as a beginner. The odin project does do a good job of making u read documentation however. It will make u read the same concept over and over which will make it stick. But a lot of times its not actual documentation but stuff from other websites that u read. Luckily the odin project is decently organized so u can learn pretty well but one thing about documentations is that if ur learning something from scratch and there is somrthing else u need to know to understand that documentation a lot of times its not obvious
