Grace is always simple, and never complex. Also, it is spare and uncluttered.
There is no effort in grace, and no agitation, since grace is a sign of and confers peace. But there is a type of grace in pain, called stoicism
Roughly paraphrasing Abraham Lincoln, most have it some of the time, some are graceful most of the time, but none of us has it all the time. Another true (but unrelated) cliché is, if you get a little bit you're going to want some more.
