My general advice on how to become a “good looking” guy:
First – get yourself in great shape. This one is a no brainer. A fit physique is an attractive physique. If you weren’t blessed with a beautiful face then the least you can do is build a lean, muscular physique. This alone will put you into an elite category.
Next – upgrade your style. Most guys dress like complete bums and it really doesn’t take much to separate yourself from the pack. Just remember to keep things simple and focus on dialing in the fit of your clothes. Pay attention to your footwear as well.
Grooming – a good haircut can make a huge difference. I highly recommend developing a relationship with a good barber in your town.
Also, spend the extra 5-10 min to keep your nails clipped, nose/ear hair trimmed, and teeth clean. It’s silly to even mention this but you’d be surprised.
Attitude – this one is very important. Stop whining and complaining about your life to anyone that will pretend to listen. Shut this part of your brain off. Focus on taking action and winning. Do what William James (father of American psychology) did: 
All of this stuff is simple but not necessarily easy. The good news is you CAN change and the power to transform yourself is in your hands.
