We need to camp higher on the North side because the technical difficulty of the North Ridge is far greater. The weather on the North side is traditionally worse with higher winds and greater snowfall. I fell in love with the sport and decided at that time that I would pursue a career in outdoor education. I strongly suggest that you seek professional instruction. It will save you years of trial and error, possibly your life.
Some folks have more natural ability and more depth of experience.
Certainly, extensive prior experience at altitude and other extreme adventure experiences are required. Both prep your body and your mind for the challenge. I would suggest that you start with climbing in a country like Ecuador, build on that with an expedition to Peru and then climb another 8,000-meter peak like Cho Oyu. Sounds like the perfect formula for me. I really wanted to reach the summit.
