It’s exhausting to be constantly “on”. In extreme cases, I can think of comedians who privately battle depression, but while in public maintain their irreverent persona to the joy of others.
It can be similar in business affairs, in keeping up with the Jones’s, or even in maintaining a functioning household. If there’s no time for full relaxation or decompression, then you’re just “on”, and eventually you’ll burn out.
