Agreed!
We should do for ourselves what we can.
You don't need a mechanic, an IT person, a plumber, or an electrician for most of the routine repairs that are needed.
Our cars mostly need maintenace and replacement of wear items, which is usually pretty simple.
As a society, we have become remarkably incompetent and lazy.
It is always fun to have done something yourself, and have the satisfaction that you've done it right.
