The Internet gives you access to a lot of material, and it's fun to sit and read. I go to something like Wikipedia and look at different topics... I find the subject fascinating. I like to read about concepts and mathematicians.
Professional players work almost every day, for hours on end, and the emphasis is on the word 'work.' It can be with a partner or it can be alone, but professional chess is always a pursuit of something new and surprising.
I was reasonably interested in mathematics in school. Typically what happens is... when you start playing chess, it takes up a lot of your attention. But about 10 years ago, I found that the Internet is very good to start learning about a lot of subjects.
