We are high earners, but do everything ourselves while our neighbors outsource - lawn-mowing, gutter-cleaning, window-cleaning, ironing, house-cleaning, car-cleaning, tree-felling, household repairs...you name it, we do it! We have kids and I sometimes (OK, quite often) wish that we had help from outside. Yes, we can afford it, and yes, it would make our lives a lot easier, but we have been brought up to believe that money is precious and we should clean take care of things by ourselves.
But...having said all that, I actually admire people who can get help in when they need it (if they can afford it, of course) and are able to prioritize their own time and happiness over financial gain. I guess I, personally, just would feel guilty paying somebody to do jobs that I can technically do, and also it means that DH has to keep working for longer in a job he hates, I feel that we shouldn't fritter the money away, no matter what it takes. I'm not saying this is a healthy attitude! It's just different people have a different perspective and different priorities. Do whatever works for you :)
Plenty of people have said to me that I should get help in, that it's crazy what we try to do, but it's a mindset for us. We don't expect to have this kind of income for much longer, so anything we can save is important.
