Okay, bear with me here, as I try to explain what it means to me.........very tired, so we'll see if I even make any sense.
To me enough means all you need. Sweet and simple. No more is needed. Whether it be good or bad enough, you need no more of it.
If it's good, you'll likely WANT more, if it's bad you'll WANT less, but the fact is, either way, you're full.
