What can you do.. if you have an IP and someone's email?

I want to find out their password for their email..
Don't ask why, Im just getting revenge.. This guy tried
to hack me -.-'

But, I have his IP & Email.
So, what is an easy way.. For me, to hack into his email?

I don't know much about hacking.. So, I know this is a noob question,
But I only want help from the best.


Thanks,
