hearts

what is a heart? why does it hurt when there isn't anything physically wrong with you? i am having difficulties understanding this concept. i know we each have a chance or a variety of chances on love and life, but do we really appreciate it? do we really give it our fullest or do we just sit by and let time fly? i think we let time fly, and we shouldn't. we need to take control of time to take control of our hearts.
time is a powerful thing and time is wise (El tiempo es sabio) but when do we really get a chance to take control of time? i think i am in a dilemma that will continue throughout... maybe none of this makes sense to you because it doesn't really make sense to me...
hmmm hearts=time=hearts??
