"Be careful what you wish for, you might get it":Is what my mum used to say. Meaning, you might get it, and actually not want it. And what was the effort for, the tears or the hope, and you actually don't want it.
I really like it, that you are so wise, for only 19 years old. I'm twice your age, and I presume I am also wise, but it is really good to figure out early, to build yourself on yourself and not on others.If you build yourself on yourself, the other person will be an addition in your live and you can love them for who they are, and not for how they make you feel and you will know if you want them or not.
