Not really a blog, but it's always a good reminder. It's easy to forget about these important things when we are overly focused on our goal. Although it is difficult to define "success", I do agree that successful people tend to have a positive attitude.
Note: Btw, this does not mean you should not watch TV or play games. For example, I enjoy playing Crash: Bandicoot with my son but I set time limit and only when the term closed.
