You know that you have to stop traveling when:
1) You have to start dating the entries because there is only so many ways to say that you are at a layover
2) You start recognizing and feeling a sense of comfort at particular airports
3) You have memorized all the free hotspots for Wi-Fi (even if it “borrowing” from exclusive lounges that you do not have access to)
4) You know where some of the few coveted outlets are for your computer
5) You know by which gate number some of the favorite eateries are
6) You start getting this déjà vu feeling like you have done this before sometime in your lifetime
