Be an attractive person.

A guy who is desperately seeking women is not attractive.
A guy who cares about his family, friends, surroundings and those around him is.
A guy with good habits, job, language, skills and grooming is.
A guy who is capable of taking care of himself, is independent, reliable and becomes the pillar of support to those around him is.
