Best way to get that dream network manager job you want - is to get a lowly job as an it helpdesk person, or an it technician in a school for example, do 3 years of work, work your ass off, get your employer to pay for as much training as possible - then companies will think "this person looks like he could manage our network" after you put in a CV full of experience, showing not just it skills, but people skills as thats just as important.
Show that you know what your doing, and you can deal with other people, and you work hard, and youll get a job easy.
