If you live in the USA, you should be living your best life, right? What is the origin of that phrase anyway? 'Living Your Best Life'. We only get one, don't we? Unless these people who say this know something the rest of us don't.
Some people aren't living their best life, however. Spare a thought for them who are living a truly miserable existence. But maybe it's not so bad on the outside. Maybe people see their life and think "It's not so bad" but they don't know what's going on inside their head. Maybe it's a case of they have to deal with it themselves? Get themselves out of whatever rut it is they are in.
We can only speculate.
I hope your month hasn't been too trying and you are still keeping calm and carrying on.
