Don't reinvent the wheel

Meaning: Don't waste effort on solved problems.

Origin: An American business metaphor from the mid-20th century: the wheel has already been invented, so there's no point doing the work again. One early example, a 1956 report on how researchers and executives use information, speaks of avoiding "re-inventing the wheel."
