I don't know if it's wrong, but it's perfectly understandable. Quite a few people go through life with a feeling that there is no sense, no meaning, just... plodding along and going through the motions, so to speak.

I think it is a 'bonus' to have a motivation or anything that spurs one on (dreams, passion or whatnot). But not everyone has the luxury to have a dream to sustain them. Just my take anyway.
