“Plan your dive and dive your plan” (scuba diving adage)

“Plan your dive and dive your plan” is a popular diving adage, cited in print since at least 1970. A carefully planned dive that is dived according to that plan can be a successful dive.
 
The saying “Plan your work and work your plan” has been cited in print since the 1880s. “Plan your trade and trade your plan” has been used in finance since the 1990s.
