To be honest, none of these sound good. Perhaps this is why no one else has commented here yet! Let's improve these. Here's some suggestions for alternatives:
1. You only live by your emotions. (= you just use your emotions to make choices).
2. I'm attracted to various people.
This sounds dry and cold. Maybe we could use: I'm into all sorts of people.
3. I'm into people with different looks.
But I think that in order to put 2 + 3 most naturally, keeping the poetic kind of feeling of "heart," we would need something like:
I fall for all different types of people.
or
I don't have a "type."
Hope this helps! You have good questions, and I think you'd benefit a lot from a lesson with me—take a look at my schedule.
