It depends what you consider a waste of time. Well chess, like art, music, or poetry, has the power ro make one happy. If you do not enjoy feeling happy, then you might consider chess a waste of time. CHess has the power to make one happy or sad depending on the way you handle it. If you consider emotions a waste of time then everything is a waste of time. It depends on you completely. And I also agree with other members who have posted things like: beauty can be expressed in the form of chess, or what is considered a waste of time. anything could be a waste of time, or even Yes! But what isn't a waste of time."
It all depends on your opinion. WHat do u consider a waste of time. That is what matters.
I also know that look is spelt look and not lok, I just can't type- also missed out in the typing stakes as well- can I sue for a wanton education ?
I used to work for a newspaper, and one of our editors told me that people with advanced degrees are the worst spellers. Also, I'm not sure you wanted to use the word wanton.
