Yes and no.
Over thirty years of strapping into aircraft and still enjoying it. Had enough experience of exercises, deployments, TACEVAL, MINEVALs etc before marrying and raising a family so knew what to expect.
Good fun and good friends, lots of travel, reasonable pay, reasonable security of job etc.
Still get totally hacked off with lackof kit, poor leadership, lack of recognition, lots of deployments etc but still doing the job that I'm paid to do, or is that an old fashioned idea?
Life is what you make of it.
i.e. balanced advice not just "I got hacked off with it" or "I had a good time". I probably wouldn't advise on a long contract but that seems to be the modern way with two or three career changes for this generation.
