Friendship is a very taxing and arduous form of leisure activity.
Mortimer Adler

Fundamental ideas are not a consequence of experience, but a result of the particular constitution and activity of the mind, which is independent of all experience in its origin, though constantly combined with experience in its exercise.
William Whewell

Walter Pater

Happiness consists in activity. It is a running steam, not a stagnant pool.
John Mason Good

Happiness consists in activity. It is running steam, not a stagnant pool.

Housework is the only activity at which men are allowed to be consistently inept because they are thought to be so competent at everything else.

Xun Zi

Jim Wallis

I don't think you can lightly paint a picture. It's an activity I take very seriously.
Howard Hodgkin

I don't want to sound pompous, but I really think your gender doesn't necessarily dominate your sexual activity.
John Lone

I guess he wanted to see a little more sexual activity because in real life, in bed I think less is more and let the woman come to me. Frankly, I don't even need a woman there.
Garry Shandling

I hadn't accepted he was seriously ill. The idea that someone so close to you couldn't wake up was utterly incomprehensible. Then the doctor came in... Maurice had no brain left. There wasn't any activity at all.
Robin Gibb
