Tzenin like others have said lets see how you are going in a years time.
I have 9-10 days off per month half of my layovers are 48 + hours and some of my flights are 45 minute turnarounds and I still get very tired. I just did a 5 hour flight had a 24 hour layover and flew back and slept for 13 hours. All off your flights will be alot more than 5 hours.
Do you have any idea how hard it will be to do a 10 hour flight. Have 12 hours rest ( remembering you have to get to and from your hotel plus get ready for the flight back so there goes a couple of hours) then fly back.
