Calibri is a font. 12 point is the size.

I always start a new document in Calibri 12 point. If a client sends me a newsletter to rewrite, I first convert it to that.

I don’t really know why, I just feel most comfortable.

I also write out loud. And I usually wear a hat.

These are all little things you may not notice, let alone care about when doing whatever it is you do.

But try to pay attention to what does matter to you in particular. Then optimize your work environment to fit that as best you can.

If my experience is any indication, you’ll be both more productive and more satisfied at work.
