What is contentment?

How do you know when you have hit a rut? Or if you're finally somewhat content with life? By definition it means: "enjoyment of whatever may be desired". But I'm not satisfied and I do want more, but I feel that I have found some balance and focus. I don't feel as edgy or stressed anymore. Maybe I have just finally started letting go of the little bullshit matters. Or maybe, this is the quiet before the storm and I'm about to hit a major life-shaking event. Either way I think I'll enjoy it as best as I can while it lasts.
