The idiomatic phrase "follow your nose" means to trust your own feelings rather than obeying rules or allowing yourself to be influenced by other people's opinions, or to make decisions by thinking of how you feel about someone or something instead of finding out information about them.
鼻に従うとは、自分自身の直感、本能、勘にしたがって行動することを言います。
I didn't have any experience with that, so I just followed my nose.
そのことにはなんの経験もなかったので、ただ勘に頼るしかなかった。
Take a chance and follow your nose - you may be right!
I tend to follow my nose when I judge a person.
直感で人を見分けていることが多い。
