If you have to ask whether or not it is something you want to do before you even start then my advice is to not bother. Flying is a great job if you truly love flying...as you put it, if you are in awe of a plane lifting off every time you see it happen. If not, then pretty soon you will see only the bad side of the job and join the rest of the Pprune ranks in whinging about every facet of it.
Some of us truly love it and even then certain things can get us down. Too many of us regard it only as a job and I pity them as it must be a miserable job to endure.
