I agree with the feeling, and I want to add a few things to try to help both sides understand.
I don't think it's appropriate to say that "life is made of". Admittedly, "life is full of", and if you can enjoy those menial tasks, reach that "zen" level as some say, that's great. In that case it's true that your "life is made of", and if you can enjoy it, much better for you. The less you need to live happy, the easier it's to achieve that happiness.
And in fact, most of us could learn a bit of that. Accept that we have to deal with those things, and at least try to not torture ourselves with it, enjoy it as much as possible (even if in some cases it doesn't seem to amount to much).
All that being said, I think it's also easy to lose perspective when you manage to achieve a certain degree of happiness or comfortability through that kind of routine, or when you deeply believe in that idea. In particular, I believe that's a state that not everyone can reach, and I doubt it's a matter of being trained enough or trying hard enough. Some people just have a natural need to create, or explore, or need to actively fight and try to change the world they live in, or whatever. Sometimes, that comes from inside, in the same way as hunger, or your need to sleep.
This probably sounds hyperbolic. For most people, it probably is. But this is the kind of issue that you can only really understand if you personally live it, because it is a psychological need, and that's very hard to communicate to others who don't feel the same way.
In conclusion:
I absolutely believe those who say that they find meaning in a life like this. I actually think that most people can find meaning in a life like this, and I believe the social factor is the most relevant for most people's happiness.
But I also believe there's a lot of people who can't find meaning in a life like this, as much as they try, because they have other needs, and trying to supress them it's not only unreasonable, but a nice attempt at torture. I can understand the people that says that they would rather kill themselves. Hopefully this adds a bit more context.
