both are correct... Important to me.. Important for me .. let me give you some examplese. "I want to be good at English, it is important to me" ... "'To get a good job, it is important for me to have a good understanding of English" So it depends on if it directly affects you or not... "important to me, important for me... Good luck!!

I wish I could provide a good answer that would work for you in all situations, but the truth us that a lot of usage is idiomatic. "For" can be used in place of because or despite , it can indicate "on behalf of", and it can introduce a period of time, a direction, or a small clause. This does not even consider phrasal verbs. As a preposition, "to" indicates direction, purpose, among other uses. You had better study a dictionary.

Hello moe-chan. I'll just provide you a recap. "For" is a conjunction. I.e. This doll is for you. It means when you are giving something to someone and you declare who you are giving it to. OR when declaring a reason to the subject. I.e. I want to go for a run. OR This worksheet is for Math. "To" is used when you are indicating what you are about to do, say, the action of another being or what is directed to you. I.e. I am going to take a shower. OR I cannot wait for you to come to my party. // If any of this seems confusing, please tell me. ;) ~Mera-chan~
