Too much of a good thing is...not often a good thing. In fact, it's usually a bad thing.
So I sit here, eating this "Skinny Cow" candy bar (it was 39 cents!!) thinking hmm. Only 110 calories, nice! Then I remember I've already had a few. Total 440 calories...not so nice!! That's the thing about these low calorie foods that you can buy now- often they put so little into it that you have to eat more than one, thereby defeating the purpose.
Another example, although I've never had this problem myself, is too much money. Rich people have a lot of crap to deal with...you know, like people making a media spectacle of them, asking for money, and the extra that isn't really "necessary" really has no use.
Too much water can kill you. Yes. It's true. It's rare, but it's true, mostly if you are drinking large quantities in a short period of time, or have some sort of illicit substance in your system. Too much of any vitamin can kill you. Too much exercise....well, I do believe that can kill you. Good things, when taken in excess, can kill you. It's sort of a paradoxical type of thing, but it's a really important thing to look at, nevertheless. I can't actually think of anything that is good to have in excess. Too much food is bad for you, too much sleep is bad for you (it's called hypersomnia), on and on. Even too much positive thinking....it's called narcissism! That's one I'd like to get rid of. Alas, it's hard to tell when something becomes too much, rather than too much, or not enough.
One thing I've thought of....is too much knowledge a bad thing? I guess it could be, but I'm finding it difficult to justify that position. Perhaps that's one area where I'm safe, because I'm always wanting to learn more. Just as long as I don't eat too many candy bars and drink too much soda. Knowledge is power! Wait, no, power in excess is bad. But knowledge is good. Is there a balance?
Back to studying. Happy eating!
