Travelling for work is a privilege and you are not allowed to complain about it.
The sacrifice is time away from your friends and family. The bonus is also time away from your friends and family.
While I don't always enjoy being away, it creates a reluctant balance in my life. One that lets me focus on the task at hand and return to my real life with a new longing and appreciation that lasts for at least a week — I'm kidding — I love my family and home so much, but time away can be important. It is equal parts relationship and sanity preservation.
Every now and again I find myself in a hotel room bed covered in potato chip crumbs, watching late night television, clothes strewn about, missing my family, and wondering how to adjust the thermostat (and by every now and again I mean every work trip). It's not glamorous, but it's how shit gets done.
