YOU SAID:
When life is tough, you must make life tough back
INTO JAPANESE
人生が厳しいときは、人生を厳しいものに戻さなければなりません
BACK INTO ENGLISH
When life is tough, you have to make life tough again
INTO JAPANESE
人生が厳しいときは、人生を再び厳しくしなければなりません
BACK INTO ENGLISH
When life is tough, you have to make life tough again
That didn't even make that much sense in English.
