Work on your charisma
I think what they are trying to say is that, it is a process of developing certain behavioural traits that can make others gravitate towards you. Charisma is a subtle trait found in most successful people. If you don't, you lack a competitive edge to influence others compared with those who do. Honestly i think it's never to late to boost your charisma which can attract people to you like a magnet regardless your age or what is your job.
Just be self-confident. Start it with the right dressing. If you're going to work, dress professionally and groom yourself properly. Chances are when you feel good about yourself, you will do your best and hence, be more confident. Even a cheap cloths will look good if you know how to bring it out!
Maintain your focus. Try and actually the right word is do not allow yourself to be distracted by issues other than the task in hand. Easy said than done right? but common..if you can control your tears from falling down..you can control the rest of it..
Interest and attitude. Psychologist have found that people are attracted to those who share the same attitude as they do about life. Something like views of parenting, work ethics, values, relationships, welfare and even movies as for me ..it including musics.. Metallica please..hahaa. If you can find areas of cooperation rather than conflict. You'll find easier to persuade and influence others.
Responding to others. But well sometimes..i need to admit that differences make us attracted to each other huh?. Showing people you find them unique and interesting makes them feel good about themselves, and thus they feel good about you. Well you know..giving people your full attention builds a moment-tary exclusive world of "you and me". Use the beautiful eyes of yours to show attention through eye contact, a warm handshake and displaying and interest in what someone is saying.
Reaching Out. You believe in touch right? Subtle touches are good if you are careful and sensitive about the norms governing what is appropriate and comfortable for most people can have a powerful positive impact giving a message of "i am a warm person"..but take a caution and do homework as the gestures are not welcome in some cultures..you understand what i am talking about right? :)
Be comfy in your own skin. Being comfortable with yourself is how you want people to perceive you. When you dress appropriately and carry yourself confidently, you will feel your best. In turn others will feel good in your presence and find you more attractive and charismatic. Shows in your posture and your gait. Practise maintaining eye contact as it indicates that you are a confident person.
