joie de vivre

リーダーズダイジェストの1月号に年の始まりらしく "10 POPULAR RESOLUTIONS" と題した記事があり、その６番目はSMELL THE ROSESと書かれていて、以下はその説明文です。
Lost your mojo? The easiest way to kick-start your joie de vivre is to do something outside the box.
Handy Hint: Remember too that small is beautiful and focus on life's minutiae, like a great song on the radio, a tasty peach, your friends' thoughtfulness or an unexpected invitation.
"mojo" と "joie de vivre" は外来語（？）の様で、意味が分かりません。まず "mojo" を辞書で引きます。

次ぎの　"joie de vivre" は英語ではなくフランス語の様ですが英英辞書に載っているか見てみます。
・OneLook Quick Definitions: a keen enjoyment of living
・Dictionary.com: French. a delight in being alive; keen, carefree enjoyment of living. Origin: lit., joy of living
ほとんどの辞書に意味が載っている事からして英米人にも "joie de vivre" は常識の言葉のようです。
