My crush always makes sure they say hi to me, like always and everyday. Even when I'm not noticing or giving them any attention, they stop what they're doing and make sure they say Hi! or something XD They don't talk to any other girls besides me.
Being particularly goodlooking is a challenge by itself. My suggestion would be to stick even more to values and activities of substance than others around you. That will not only help yourself but also help your admirers.
