As it is said, have a nice day!

利茶亜努
ri.cha.a.do

Literally: advantage/benefit – tea – “next in rank” – diligence/effort

Alternately: When in doubt, use your common sense. Persistence and effort are the most reliable keys to success, but using your noggin is a good plan B. When you can’t work harder, work smarter.

Notes: 利茶 (richa) is an obscure antonym to the more common 無茶 (mucha), “absurd.”
