I love this subject, so thank you! a) if you study 10 different subjects, it would be quite difficult to reach a very deep comprehension of any; on the other hand if you choose /less/ subjects (1 or two) you might gain /more/ meaningful knowledge, and maybe bring your own contribution, which in this case would mean much more satisfaction! b) if you can't forget the myriad of not useful information that you might encounter over the Internet, from TV, etc. your attention will be overwhelmed with /a lot/ of details, and you could have difficulties to concentrate over the /fewer/ but important things that really matter to you. The saying is this: no drain, no brain. What is the point in having 10 friends, when you can't spend some meaningful time with any of them, and so only stay at a superficial knowledge, without enjoying true friendships ? Better /less/ friends in this case.

"less is more" is a neutral words. its' meaning largely depend on the surroundings. in certain condition it is undoubtedly correct, but in another condition it isn't probably correct.. for example. if one want to loss weight, eating less probably means more reward, because eating less probably help him or her to loss weight.....in addtion, one, who has less desire, probably own more peace in his or her mind... just like the ancient saying: no desire will make one become as stronge as steel... under other condtion, less is less, more is moe.. for example. one want to improve himself, if he or she pays less endeavour, obviously he or she don't make more rewarding. "less is more " should be regarded as the attitude to life in reality....after all, trouble is more, however happyness is less. if the trouble is less, we will have more happyness...

Homework, huh?
