How can you say it's all a waste of time spending it on watching football games, like am just getting to know about this for the first time from anyone and it happens to be you. Perhaps you are not a fan of football hence your opinion, therefore if that's the case then am not aback at your statement.
I think he's someone who're very competitive and not want to do something that will not give any financial benefit for him, which I think understandable. You know right the current society value money is the most important thing, so many people are really obsessed to make money even though they need to sacrifice their free time, friends, fun, girl friend, etc.
Everyone have free times, but grown men choose to use the time to study, learn or work.
