如果是表达对别人的祝愿，”你一定会成功的。“，则我觉得英语可以用”The victory sure belongs to you.“，德语可以用”Sie sind ja erfolgversprechend.“如果是一种陈述，”你一定要成功“，那么我觉得英语可以用”You must make sure that you are to succeed.", 德语的话“Damit muessen Sie den Erfolg zu haben.”

We are certain that you will succeed. We are certain of your success. It's certain that you will be succeed. You are certain to succeed.
