Tech support is needed when you are not able to solve a problem, because you are not an expert in it.
Hiring a plumber, getting your home painted, or servicing of your car are examples of tech support if you are expert in none of these.
This, of course, does apply to our brains.
With only a cliché: we are the biggest experts in handling our brains and yet most of us look to others to make us feel loved, respected or even good.
You don’t require tech support for your brain. You’re the expert to deal with the malfunctions, if any, that arise.
