As the other said above, you are your best teacher. I would recommend that you rely upon others only as a source for information on where to look. If you see someone who you think is knowledgable in the path you wish to pursue, send them a message asking if they know any good books or websites that you can use for research. Most people will be more than willing to guide you in the proper direction.
Also, remember that Google is your friend! It's an invaluable resource for finding information on practically anything. Just keep in mind that you can always go to the 2nd, 3rd, or even 4th page of the search results.
