求英语翻译高手帮忙翻译一下以下这段话，最近有个外企面试，拜托各位了！！

There's an old saying:" Life begins at thirties." Now, I'm 25 with five years left. It's a great opportunity in my life change. To be honest, it's not only a picec of job, but a career. I will make every efforts to fight it.

As a Chinese saying goes, A man should be independent at the age of thirty. I'm now 25 years old and only have 5 more years. I regard this interview as a good oppertunity to upgrade my life. It's not only a job to me, but also a career. I'll brace every nerve for a supreme effort!
