Any tips on mountaineering for a beginner?

Every now and then I keep getting urges to go on adventure trips, and climbing the Mount Everest is the ultimate adventure, and was wondering if at all it is possible for a novice like me with zero experience to give it a shot. If yes, how long would it take me to get prepared? How healthy should I be? What kind of training goes into it? Please remember I'm a total novice, only had been on trekking trips in school and college. And I've been anemic for the greater part of my life. So what do you girls and guys have to say? Any tips or advice?
