I think that it all depends on where the motivation comes from. If it's just to save money, that's nice, but the need to do it disappears when you have enough to spare.
For me, I tend to want to fix things more the more my job is boring and I'm not able to work on new things or improve existing ones. I'll then take some satisfaction on actually being able to affect change, even if it is in my own environment. It can be a bit therapeutic.
I will, however, delegate some work when I don't have the tools or the means to do it efficiently. I had an alternator failure. I could replace it myself, I know how. But the car in question has it in a pretty difficult to access location. It is doable but would probably take me the whole day (if not more) with just a jack and stands. So I sent it to the mechanic.
And yes, if you are falling behind on your repairs or if you have to spend most of your free time to do it, it's not worth it, you need more hands. Also, if you actually don't have free time and you would use that time to earn more money.
