I don't see anything that really distinguishes it from any other profession in most regards. I understand there's a risk of depression and substance abuse, but that's just life. I also understand there's not a huge chance for on the job satisfaction, but that's true for most jobs.
No.
No, it isn't.
If you find the job/lifestyle that's right for you, the odds are much better.
That MAY be law for you, but I don't get the vibe that you really understand what law is all about, and therefore I don't know how you're judging it. Mind you, it's probably fair to say that most people end up in a job that isn't suited to them at some point in their life and then it's a challenge to get out of it. I'm not immune to that at all but you know what, if you find it happening to you, make changes. Don't stay in the same rut. But I guess sometimes you just have to do it, to get it out of your system. So go do law and I hope you enjoy it and it's suited to you. But research it some more first.
