Though native English speakers use "be important to doing sth" daily, there are still a little odd for me to say like that, what do you think of it? Will you use "be important for doing sth" ? It sounds much better. Really?

is important to do something is right. It is important to make sure your breath is fresh when you kiss her.  so do u agree now? heeee
