translate English to French: "I had to master every aspect of running the business before I could start to train people in what I did and before I could start to put the systems in place to ensure that things ran consistently."
Mais il me fallait maîtriser tous les aspects de l’exploitation d’une entreprise avant de commencer à enseigner aux autres ce que je faisais et à mettre en place les systèmes pour assurer un fonctionnement uniforme.
