If you PT like mad (real world like Cross Fit, not pretty like body building...) you won't go wrong. Spherical endurance (mental and physical and even spiritual, for every imaginable and some unimaginable physical events) is the way to look at it. If you have to draw on your mental reserves 15 minutes into the first PT session, you didn't train enough.

For my money, the best trait you can develop is selflessness. Maintain a positive mental attitude ALWAYS, help others and work together even if it makes your own life harder. Then train so you can handle "harder" (and really apply yopur imagination to what "harder" means!)
