+ 2 Votes Yes you CAN :-) terryhugill December 23, 2012 at 4:32pm PST I don't see any barrier for you other than your level of passion. They say it takes 10,000 hours to master anything. Are you willing to put those hours in? If so I don't see any theoretical limit. As has been intimated you will have to start in an entry level permission but if you have the desire, that should not be a problem. A lad I know started (admittedly a few years earlier) with no qualifications two years a go. He showed tremendous passion, took a pay cut from his well paid but under fulfilling admin role, he has passed some MS qualifications and is now a thoroughly reliable and respected member of second line support.
