I can't speak to grocery stores or doctors, but the idea that you should be abele to fix everything in your home isn't that far fetched.

Perhaps the modern world has made things appear otherwise but even the most average adult has the capability to do basic vehicle maintenance, plumbing, simple electrical work, basic carpentry and so on. In fact even if you do live in an urban area you might be in for a a bit of regret not learning those skills when you call for a contractor or electrician but no one is available for months due to the ongoing labor shortage.
