The real world does not reward stupidity. And trying to build something worthwhile for yourself while frittering away each business day in a haze of email, IMs, web sites that don’t directly relate to what you are doing is stupid and will get you nothing but tears and heartache. Letting email/IM/twitter/browser run full bore during the periods of the day you are supposed to be creating something is exactly as stupid and criminal as driving a car while on your cell while texting while watching a dvd player. Someone is going to get hurt, and you’ll be to blame.
