First off, Viesturs was always extremely well prepared in terms of physical conditioning, equipment, planning, and his choice of climbing partners. Secondly, he was always generous when confronted with incredibly challenging conditions...if another climber was afflicted with pulmonary or cerebral edema Viesturs would be the one to sacrifice his own climb to help that person survive. Lastly, and perhaps most important, each mountain that Viesturs attacked would be done in stages that were well thought out and he never thought about more than the direct task at hand...that is how he survived on over fifty expeditions to 8000m mountains.
When you're confronting your training and preparations for school in this next week, simply focus on the task at hand and let the rest take care of itself.
