Enough
Enough: occurring in such quantity, quality, or scope as to fully meet demands, needs, or expectations.
"I wish you ..... enough." What a nice way to say goodbye, that is what a fulfilled life is all about, enough. I don't recall anyone ever using the word to say goodbye, but it is so appropriate. Not, have a great life, it probably won't be, but what a nice wish, that you have enough.
I have used that word many times and never really given it any thought as to what it actually means. It's a very simple word, a comfortable word.
I doubt that I will start using that phrase to say goodbye, "I wish you enough," people would look strangely at me, but all that goes with it has a very special meaning.
What are your goals in life, "To have enough." That says it all, enough.
