I feel that I am much freer if I'm on my own, but I'm sure that there are a lot of painters who would perhaps be even more inventive if they had people round them...

Travel, in the younger sort, is a part of education; in the elder, a part of experience. He that travelleth into a country before he hath some entrance into the language, goeth to school, and not to travel.

Only men must beware, that they carry their anger rather with scorn, than with fear; so that they may seem rather to be above the injury, than below it; which is a thing easily done, if a man will give law to himself in it.
