Brain or heart?

I always tell my friends,
go with your heart whenever you have difficulty in making decision,
just go with your heart,
it will give you the best decision..

However, I realised..
this is not the first time anymore,
going with your heart while making decision hurts a lot..
somehow we just have to choose whether to make decision
with our heart or brain..
your brain always go against your heart..
telling you the total opposite things..

That's why we always struggle when we have to make a decision,
and we couldn't deny that the answer of the heart is always the one we wanted the most..
Sometimes, the situation just don't allow us do choose what we wanted..

Perhaps, those rational thinking is in our head !!
just sometimes we are escaping or ignore it..
I just have to be rational and just follow what my brain ask me to do..
Not the heart.
