Do you intend on acting with your mind or heart?

I plan, I plan different outcomes to different situations so I use my head, one of my weaknesses is that halfway through the planning I often just give in to my emotions

Business; thought.
Relationships; emotions and feelings.

I think a good mixture of both.

Use your heart to access your intuition. This is particularly helpful in a situation where you don't really know somebody very well and you could be taking a risk by receiving their help or whatnot.

Mind, I can lie and pretend to be touchy feely and pretend that everything I see is the end of the world. However I would be lying.

I kiss with my heart, but act on logical rationale for everything else.

I'm going to be a bit naughty and say that I don't think the distinction between thinking and feeling is as clear as some people like to say. To start with, the distinction between thinking and feeling is an arbitrary one. Own brains cannot know the difference. If we choose to behave as "logical thinkers", we do so because of emotion. Perhaps we are taught to be ashamed or dismissive of emotionality, and consequently we shut emotionality down. If we behave as "emotional feelers", perhaps we do so for intellectual and logical reasons such as preservation of our mental well-being through the expression of our creativity.
Logical thought requires a base of emotion, because logical thought such as that about morality has to be carried out with aid of a structure which we choose based on emotional reasoning. Equally, emotional reasoning requires an intellectual base to even be articulated.

When people think of the tendency to either be a thinking person or a feeling person, I think they are more often thinking about personality traits like impulsivity, empathy and neuroticism. I think these things do not necessarily link to a wealth or to a poverty of either thinking or feeling. We use the metaphor of the heart and the head to illustrate our moral dilemmas, but I think the metaphor isn't usually accurate. Although it all depends on how you define "thinking" and "feeling", obviously :P

I suppose you're now going to say I'm a thinking person, or else I wouldn't have written all that. Although a person without enough impulsivity wouldn't have written it in the first place :P

To quote the great Fritz Lang's Metropolis;

"The mediator between head and hands must be the heart."

I generally end up regretting choices made impulsively and with emotion, so the thinking solution seems better. It puts me at ease to know that I've considered all other options and chosen the one I have on purely logical grounds.

Probably both, I don't rush into anything.
But what's that saying. Even though your heart is on the left side it is always right.

I mostly act on logic.
I pretty much ignore my emotions.
