You learn how to love everyday. It's not a one-time lesson where you'd get it right the day you first learned about it. It's progressive. You just learn how to love everyday. Because each day, someone or something is going to come and screw your beliefs and make you doubt whatever you just knew yesterday. So you learn to love and love again, almost always in different ways. There's no right or wrong way to do it. You just do it, and hope someone out there will love the same way you do.
