Throughout life you will meet one person who is unlike any other. You could talk to this person for hours and never get bored, you could tell them things and they won't judge you. This person is a soul mate, your best friend. Don't ever let them go.
It's not about finding someone who won't fight with you or make you sad. It is about finding the person who will be standing there wiping the tears away, holding you in their arms after a fight. The one who will never leave, no matter how hard it gets.
Your Soul mate will be somebody who marks a before and after in your life. It is not the human being everyone has idealized, but an ordinary person, who manages to revolutionize your world in a second.
