Exactly. I have experienced this first-hand, and my swings are much smaller than that. The thing is, anything worth a spit is going to be hard; there are swings in "regular" professions as well. Learning to deal with them is part of growing as a professional, in my opinion. I think that there are many life lessons to be learned at the table, virtual or felt, and mental toughness is one that can be extremely beneficial to someone traveling the globe. There isn't a swing out there a pint or four can't cure!
