Quite.
To the OP - as others have said find a sector you are interested in and pursue that first, then think about how you can leverage your skills and experience to find a travelling job.
I enjoyed the first 5-6 years of business travel (mostly). I was able to go to places I was unlikely to otherwise visit (Saudi Arabia), see a different side of those I had been to (nothing quite like negotiating with Thai or Cambodian civil servants to give a clear insight into a society) and earn miles to support holidays in new places I wanted to go to (hello Tonga and Samoa).
Then my job became the same 3-4 places on repeat with increased frequency. Over 3 weeks last summer I did LHR-BLR-CMB-MAA-BOM-LHR-MAN-LHR-HKG-SIN-HKG-PVG-LHR-IST-LHR-HKG-LHR including lots of days on the ground working. Utterly horrific. The holidays are still there for me, the GGL benefits smooth the path but it is tiring and stressful and doesn't just impact you. I've lost touch with friends through never being around and most painful of all was being somewhere over Russia on a CX plane (and thus uncontactable) when my father died. Finding out by baggage carousel 7 of T3, 6 hours after he passed away was not cool at all.
