I need to decide!

What would you do if you were given a chance to further your studies?
And it's not that you're applying for it, but you are recommended by your lecturer to a professor of an institute.
My professor offered me a once-in-a-lifetime opportunity to study in Korea.
I just finished my degree and if you ask me I would say I don't want to study anymore because I am tired of it!
But if you ask me in another 4 to 5 months' time, I think I'll change my mind.
By the way, I just finished my presentation for my thesis this morning.
Just now we went to celebrate with my professor.
I was talking to my lecturer about my experience in Korea and suddenly she told me about it.
She told me to go for it.She even asked me to mail her my details. Friends who were there said this is my chance and I should grab it.
I need time.
I need to think.
I will decide what's best for me and hope I won't regret it later.
