If you don't know whether you should do it, you shouldn't do it. It's as simple as that. You have to be absolutely sure that flying is your thing. Then go for it 100%.
There are always people complaining. There will always be drawbacks. There is always a bad job with low pay. But only the people who were not really sure in the beginning are complaining now. The others just enjoy it.
btw the prospects have never been better (unless Osama strikes again), and it has never been easier to get a jet job after 200 hrs.
