ok, so imagine you're sitting at Jones Beach, bathing in the sunlight when you spot the person you know you want to talk to...
...Then imagine this - You actually talk to them! Thats right, The summer is all about getting to know people and trying new things. Its a time of re-birth. So lets start with the basics.
Rule #1 - Don't Stare - Speak! I don't know how many times i've seen two people share a series of glances and never approach each other. What's the worst that could happen other than sound? Carpe Diem!
Rule #2 - CONFIDENCE! Nothing matters to a girl or guy more than confidence. If you don't have it, all your looks won't mean anything. Let people know that you're somebody not just another person.
Rule #3 - Personality Plus! If you follow rules 1&2 the third one is almost a cinch. Though looks are what initially attract a member of the opposite sex, or in some cases someone from the same sex, If you're talking to a wall its not going to matter who you think you are!
So Follow those three steps and you'll be on your way to atleast accomplishing what most other humans can't - communication of your feelings! There are only 3 months of summer - better to have tried and failed then to have never tried at all.
