What’s the best advice you’d give to someone younger than you?

No need to hit my phone with a hammer! Uninstalled Jetpack, reinstalled and it all works again!
So my advice to the millions who are younger than me? Wait for it……
If it stops working, switch it off and unplug it. Have a tea (or coffee) plug it back in and start again.
This works for almost anything, except life support systems. (Unless you really hate the person) then it solves lots of personal problems.
So after 70+ years it comes down to this simple advice. It’s amazing how many folks disregard this simple advice!
