Playing a character is an illusion, and I feel that when you know too much about a person, possibly part of that illusion is disrupted.

We think too much and feel too little.

I feel terrible that I once put too much emphasis on material prosperity.

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

It's so much easier to suggest solutions when you don't know too much about the problem.

If I thought about it, I could be bitter, but I don't feel like being bitter. Being bitter makes you immobile, and there's too much that I still want to do.
