A Quote by Sir Arthur Conan Doyle on facts, knowledge, and time

There comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.

Sir Arthur Conan Doyle (1859 - 1930)
