Sometimes you can know too much. A lot of brainy people like Stephen Fry are quite depressive.

You can't know too much, but you can say too much.

But I sometimes think we have too much of a fixation about 2012.

A lot of shorts spend too much time setting up the idea; sometimes they meander.

Sometimes too much to drink is barely enough.

I do text a lot. Sometimes, at night, my thumbs hurt because I've texted so much, so I definitely text too much.
