Avoir des problèmes vous apprend à les gérer.
Contexte et précisions
En anglais : "If I had a formula for bypassing trouble, I wouldn't pass it around. Wouldn't be doing anybody a favor. Trouble creates a capacity to handle it. I don't say embrace trouble. That's as bad as treating it as an enemy. But I do say, meet it as a friend, for you'll see a lot of it and had better be on speaking terms with it."
