Agreed. If you don't mind not seeing your friends and family often its a great job. Key being job, that doesn't pay all that well unless you get some seniority. If all the stories of current and former airline pilots doesn't turn you off the go for it.
But if you gotta do it, do it when your young and single. If you actually want to raise your kid and not have the postman do it for you think long and hard or get out after the fun wears off when your older. Thats the beauty of life, you can do it and if you don't like it after a while, or your priorities change do something else. No one says you have to do one career your whole life! The key is priorities. What are yours will be a big factor on how rewarding your career in the biz will be. Good luck!
