Follow your Head or your Heart

It is not easy to do the right thing (at least, what i think is the right thing to do)... no surprise here.. My head and My heart, why wont u guys just get along...

Should I stick to what my head thinks is right, even though my heart yearn for something else... After all, that's what intelligence are for, right?

Or should I just follow my heart, and set myself free from all the rule, and logic my brain set...Shouldn't we be true to our heart...

I never care about the society's rule so much, (especially the one set by tradition thai society), which is by itself another topic to be debated on. But what about the rule that my head set for me, should I follow them.

I'm afriad I will never know the right answer to this question... or maybe someday I will

P.S I asked this question when I first watched Spiderman II, half a year ago.. Think i will post it here today, since this question just pop back in my mind again
