Not everyone is good at self-learning. Thats like saying we should all be graduates because there are schools everywhere now.
A lot of people are good self learners because they have been taught wrong. Especially in the US. It's crazy because naturally we get it and do it. If you hand a toddler who can't read, a book. They'll flip through the pages, look at the pictures. Then when you go through it and read it to them they'll point out all the things they saw and remember and that helps it sink in.
You don't have to get a book, or textbook and wait for it to be spoonfed to you, or cram it all at once. What you should do is open it up, look at the chapters, the sections, if there's pictures, look at the pictures, you'll formulate questions in your head "how do I do that?" "What's that about?" "What does this mean?" "Who's that?" Then you go and read it and ask you read you'll find the answers to your questions and if you have a teacher go over it or through it with you or to you those questions will be answered and you aren't just in the dark having new information fed to you.
