How to love someone
Consider whether the person is worth your love or not.
Love requires a significant emotional investment. While loving someone is not always a matter of choice, it may be worth taking a look at the connection you have with a given person and thinking how loving them might affect you.
While this step may sound like a warning, it's actually a positive step towards loving them. If you struggle with feeling love, justifying it on a logical basis can be a positive step forward.
