The time you enjoy wasting is not wasted time.

Bertrand Russell (1872-1970) English mathematician and philosopher

(Misattributed)

Attributed to many modern authors, including John Lennon,  T. S. Elliot, Lawrence J. Peter, and  Soren Kierkegaard. Most often attributed to Russell. it is actually a comment/interpretation by Peter in Peter's Quotations about a different Russell quote ("The thing that I should wish to obtain from money would be leisure with security"). In turn, the words were not original with Peter. More information.
