"Let yourself go
Relax and let yourself go
You've got yourself tied up in a knot
The night is cold but the music's hot"
I think Ginger has wisdom for all of us right about now. Let yourself go, or "let it go" to quote a more contemporary role model.
The thing is, a lot of times it's not up to us.
Annoying colleagues? You don't have to make their lives easier. You just have to be civil, unless they go from annoying to rude.
Colleagues trumpeting their own fabulousness until you feel as though you ought to climb into a cave somewhere? Congratulate them if you can. Ignore them if you can't.
Christmas/holiday prep? Yes, it's stressful. Do what you can and leave the rest. The world will survive.
Start living life in 3D instead of 2D (computer screens). Maybe you want to take up knitting, or skate, or hike, or juggle.
Let yourself go.
