I suppose it is a different generation thing.
I simply cannot think of any job that I was able to do for myself that I ever thought of getting somebody else to do for me.
It is simply something that would not occur to me.
The things that I might need to do for myself, I just do because it needs to be done.
That's a commendable attitude but again, some people barely have any spare time due to work/family/whatever and would rather spend that time on something else other than cleaning their oven.
