Where are you getting this overly broad statement from? Don't imply your own particular experience is what even comes close to being the case in other situations. People are different. What floats your boat or my boat is not universal or even close to that. There are plenty of people doing plenty of interesting things (or for that matter ordinary things) that are way more exciting than 'the kids'. And no the answer is not to pour energy into 'making your kids project more interesting' either. I'd even say it's the opposite. Don't feel you need to hand feed kids the experience. A parent has many responsibilities not just giving 100% to their children (or even close to that) the way I see it (and once again from my experience going through that with children).

Now that said sure if I worked at a job that I didn't enjoy or did unimportant work that was boring I'd probably think it's pretty exciting and find kids very interesting.

There's a cheesy saying that applies here. The grass isn't greener on the other side, it's greener where you water it. If your children aren't there most interesting thing you do in your life, then water the grass on that side of the fence. You owe it to them and yourself. Otherwise, why bother having children in the first place? 20+ years and hundreds of thousands of not a million+ invested in a project that just isn't that interesting? What a terrible waste.
