There are many, many worse jobs in life you could be in. I did half a year of training of teaching English, so I know what I'm talking about
If you are prepared to be working extremely hard (possibly for little respect or gratitude from the people you are working for) for long hours with not much rest, going through constant time changes, having to smile and be pleasant to some mannerless, arrogant and dispicable people for 12+ hours, travelling the world and getting payed for it (no matter if it isn't much), being able to escape from snow and cold during winter to somewhere hot and tropical for a few days, having some wild parties and drinking hideous amounts of alcohol on a long layover, meeting fantastic people and then coming home with all the memories from it all, then I think you will enjoy this job no end!
But just remember, not everyone is well suited to this, and as HUE JORGAN said, you have to take the good with the bad.
