For me, the simplest example was changing the oil on my truck; I could do it, but found it more than reasonable to pay someone else $20 to do it.

For other cases, sometimes I wouldn't mind paying someone else a good market rate -- drywall work comes to mind -- but the mental overhead of contracting and scheduling is currently high enough that I end up just doing the unpleasant work I'd rather pay someone else to.
