Love is something that we cannot see, hear, smell, touch or taste. We can only feel it as best we can. Love is infinite. There is no end.
It's something that a human cannot decide upon or change. You can't make yourself love someone or make yourself not love someone. If you feel it, then you know it.
Love is unpredictable. You don't know when it will hit you or when it won't. It'll just happen. It's like finding a five dollar bill on the street: It'll be hard to find, but you will, in time.
You can't wait for love. You can't strive hard to find it. Just try, but don't put your all in it. Cause love will want to hit you when you are least expecting it.
When you are in love with someone you don't try to please them. You don't buy them fancy things, or anything materialistic. You just love them as best you can.
When you find someone you love deeply but you can't have, all you can do is be happy for them. Don't try to win them over. If you really love them, you'd let them be happy. What ever that happiness may be.
Love is the only thing in this world that keeps man-kind together. It is what's holding us together. Without it, where would be be?

It's the brief and simple definition of love. People make love so complicated, when it's as simple as that.^^^^^^^^^^^^^^^^^^
