You should never go to a meeting or make a telephone call without a clear idea of what you are trying to achieve.

Strategy is figuring out what not to do.

An artist's studio should be a small space because small rooms discipline the mind and large ones distract it.

Deciding what not to do is as important as deciding what to do.

Do not try to do everything. Do one thing well.

The most important decisions you make are not the things you do, but the things you decide not to do.
