Flying is like a disease with no cure (in a good way!) - for those of who catch it Properly, there is no cure except flying for a career. I love it - every single day. Of course, like any job, there are days when you think "will this ever end" but there is never a day when I genuinely dislike my job. It will be a massive salary drop for you, but compare that to lifestyle and then decide if its right for you. I was always that kid who would press his face against the window at the airports watching aircraft land & takeoff, face full of excitement - and I have apparently had 'itchy feet' since I was able to walk - so its a perfect match for me!
No regrets, after 6 years I still love it - have done both Short Haul and Long Haul - and will be flying for many many years yet.
Go for it
