1) deoderant always....smelling next to someone in a cockpit for a few hours is an all too unpleasant experience. An under shirt always works well.
2) dont take the huge leather suitcase with complete Jepps and 8 pairs of Kim Jong Ill sunglasses with you on the 3 hour Nav in the bush.
3) show respect to everyone (filter out the BS) because you never know what connections people may have
4) Dont crash
Have fun
