Paper is good. Serious study has to be done from paper. Compliment the paper with good Internet resources and you are in a position to learn lots of stuff in an efficient manner. And my use of efficient is in units of time. If wanting to save time makes me easy , then I'm easy.
Time is our most precious resource.
Since you are going to lose it, then you might as well use it. One sells diamonds for what they're worth Down on pain street, disappointment lurks Son, don't be home too late. You know how time fades away. If wanting to escape the jaws of time makes me easy , then I'm easy. The Internet is a great way to share yourself with the world.
