It's fine to get rejected once. But thrice in a row? That's altogether inexcusable. You should have done something to yourself before you let yourself be dumped three times in a row. Surely, the guy behind your getting (you) dumped looks hunky and cool, but it's not an excuse that you should make to yourself. Implement a plan of action now! Go and transform yourself into a charismatic guy.

1. Regulate your voice.
Try to sound more mature than your age. If you could modulate your voice a nick deeper, the better. A low baritone voice is one of the qualities in men that many women seek. Women detest immature sounding men with lots of errs and uhms when stringing along sentences. When you speak, modulate and speak clearly. Remove unnecessary idiosyncrasies.

2. Practice the movement of "cool" guys.
Cool guys move around less and smoothly. Practice it at home. Try not to slouch and practice the "cool" stance by watching the movements of "cool" guys in the bar or of movie stars who are considered sexy and appealing such as Brad Pitt, George Clooney and Hugh Jackman.

3. Learn how to stare "nicely."
It's alright to stare, but not much. You might scare women off. Staring nicely here means you should look at a woman's eyes for a couple of seconds, hold it and then release it before she does. Repeat and rinse and stop on the fourth time. Get cues from the woman's body language. If she looks uneasy with you making an eye contact with her, stop with your first staring attempt. Let an hour go by without you looking at her. With this tactic, there's a 99% probability that you will see sparkle in her eyes the next time you look at her.

4. Cut the crap out of conversation.
When conversation starts between you and a beautiful woman, don't stumble yourself by giving her praises that she would eventually get tired of. Women love compliments but hate an overzealous guy who doesn't know how to keep a conversation entertaining and instead adorns his dialogue with flowery praises.

Also, don't be the "very intelligent" guy in the house. Yes, you're a magna cum laude, but don't be a know-it-all and make a woman feel as though she's unintelligent. Once you're together, she'd know how intelligent you are and you don't need to flaunt it the first time you meet or dine out together.
