How to convert this first order sentence into conjunctive normal form?

How to convert this first order sentence into conjunctive normal form?

This is one of my homework, but it seems to be so complicated that I
really do not know where to start :(
∃x∀y∀z(person(x)∧((likes(x,y)∧y≠z)→¬likes(x,z)))
Any help is appreciated!
