Think about the IMSAFE checklist. Every pilot should be way familiar with it before they even solo.
Are you ill? Maybe not on December 1st, but if you push ten hour days followed by sleeping on floors during the winter you’ll def get sick within the first couple weeks
Medication? Are you going to be on medicine when you get sick?
Stress? Is spending an entire month on the road with a complete stranger going to cause stress?
Alcohol? Shouldn’t be a factor
Fatigue? This one goes without saying that you’ll be plenty fatigued
Emotions/external factors? What are you going to do if the plane breaks while you’re out in the middle of nowhere sleeping in a tent
