You know when someone's got it don't you. And if you haven't got it you recognise that too. Most of us are hip to what makes someone attractive. The big question is how do you get it.
I know that looks are a primary attractor, BUT without the other elements they don't count for zip! Assuming you don't look like Catherine Zeta or Brad Pitt AND you aren't about to reconstruct yourself with cosmetic surgery you're gonna have to develop your Attraction Factor.
There's no quick fix but the good news is that with a little effort, anyone can become attractive. Like building a six-pack or a shapely body, it takes time and dedication. Attraction is a quality that emerges from inside and spreads to the outside. It isn't something you can get by pasting behaviours onto yourself. If you want to attract great people into your life you're going to have to do a bit of internal spring-cleaning.
1. Be what you want to attract. This means that if you want to attract a kind and caring person, you won't do so unless you manifest those qualities yourself. If you want hot sex, you better show you're hot! Building up your own resources is a duty you have to yourself.

2. Learn to like yourself. Make a list of all your admirable qualities. Stand in front of a mirror and practice saying them convincingly. If necessary act it till you feel it. Ask yourself what qualities you demonstrate when you're at your best. Notice how you feel when you think of these. Develop an awareness of where you feel this in your body and what types of physical sensations you get. Keep practicing. If you can't do this, go on a course that helps you to gain confidence and love yourself.

3. Ditch desperation. Desperation is a nasty odour that seeps out from your pores and repulses everyone you meet other than those people whose mission in life is to 'save' others. If you need something so badly that you feel a hole in your life without it, you won't get it. Learn to fill in your own gaps instead of trying to find someone to do it for you. If you don't like your job, don't look to someone else to make you feel better. If you're in a relationship because you are scared of being alone, leave and learn to face your fears.

4. Make people feel good for no good reason. This isn't about pleasing others at your expense; it's about being nice to them for no good reason. SMILE at as many people as you can, notice the good qualities in people rather than the bad ones, let someone out in traffic, say hi to people in the park, and compliment your friends and colleagues. Make a list of all the things you like about your friends, family and people who play a part in your life. Then tell them. And keep telling them. Everyone loves to be appreciated. Spread a little sunshine and your glow will begin to draw them in.

5. Know what you want and deserve. If it's a relationship or a job you're looking for, make a list of all the qualities you want in your perfect partner/employer. Use examples of qualities you see in people every day. Keep doing this for about a week. Then go through it and pick out the five things that you absolutely must have and if they're not there move on to the next one. Learn not to just take what you can get but reject what is not right for you. Think big and you'll get big. Think small and you'll always end up with second best.
Work hard on developing your attraction factors and soon you'll be catching the fancy of people who like you because you're living your life to the full and they'll want to be around that
Only as high as I reach can I grow,
Only as far as I seek can I go,
Only as deep as I look can I see,
Only as much as I dream can I be.
