Do youy have room in your house for an entire library ?? Because thats what it wood take if you depend on books alone !! And even then without someone to explain all the quirks and differences you would be just as lost !! You need to start with one or two areas of interest to you and when you are comfortable with those,,add another !! Its just too mind boggling and confusing to try it all at once !! Is there one thing you like more than others ??
