I'm not sure whether its worth it or not. From a financial perspective, it definitely is not. You'll have to invest a lot of time, effort, and money to make a piteous salary fist as a CFI and then a regional FO for several years. You'll end up several years behind your peers in different fields, and you'll likely have a mountain of debt. Once you actually get on with an airline, its pretty cool, but I question whether getting there is worth it. Unfortunately, I'd have to say that unless you're independantly wealthy... its just not worth it.
