答：我们觉得“成人 成才 成功 ”用英语应该这样来翻译：
First of all, we must learn to be a qualified person，then be a useful/talented person and at last we will certainly get/achieve/obtain success.

我觉得这句话里的“成人”并不仅是成年人adult的意思，所以用be a man比较好。
比如鲍勃迪伦写过
“How many roads must a man walk down
Before you call him a man?”
Be a man,Be a talent ,Be a success.
