It’s Monday, it’s snowing, and it is cold. These are facts I have no control over. So using ‘it is what it is’ works here.
If I use it as an excuse for inaction though, it implies not only that this is the reality I face, but I cannot make it any different.
So, it is what it is, until you decide it isn’t.
Cheers and here’s to an empowered Monday, week, month, year.
