Of prosperity mortals can never have enough.
You're never rich enough if you can be richer.
the truly covetous have never enough!
It's hopeless! Tomorrow there'll be even more books I should have read than there are today.
Who is the covetous man? One for whom plenty is not enough.
When you have ambition, then it's never enough to win.
Unfortunately, no matter how much time you get, you can always use more.
I remember thinking years ago about getting a half special, 'When you get that, that will be it. That will be all you need to feel validated in this world.' I feel like that special was just another set.
There never will be enough for everything while the world goes on. The more that is given the more there will be needed.
You can think you've made it and yet the next day's press will always be waiting for you, the public will always ask more of you. In short, you can always do better!
You can't win enough, you can't have enough money, you can't succeed enough. There is not enough.
Too much money ain't enough money.
It doesn't matter how much you get; you are left wanting more.
You can never know enough, never work enough, never use the infinitives and participles oddly enough, never impede the movement harshly enough, never leave the mind quickly enough.
