Today, there is a direct relationship between how easy something is and how worthwhile it is pursue. If someone is batting their eyelashes at you, dying for some attention, they're not the person you should be checking out right now. Seek out the person who stands apart from the crowd, who doesn't work so hard for the approval of others. This person is not playing 'hard to get,' they are just being themselves. Strike up a conversation. It may be challenging, but it will be worth it.
