If it's because you are becoming disillusioned with the career ahead of you, then I suspect many here would tend to agree, and wave you on your way. Particularly so if you have a good job to return to, that you enjoy!
Yes, agree with 4468 if it's disillusionment at the prospect of the job ahead rather than just a training obstacle. I shared a bus with a couple of crews from a former employer of mine recently (one I enjoyed working for very much); they all looked completely shagged - run down and a bit scruffy to be honest - and they were on their way to the aircraft for the first sector of what was likely a long day ahead. May have been a result of EASA FTL's or perhaps they were all just having a bad day but it saddened me when I thought back to how the industry has changed in recent years.
