The 2 main things to consider are...
1. How much you'll enjoy it.
2. The future prospects (aka. How good is this profession for getting you money).

No point doing something you hate, also because you're probably not going to do very well on it.  And while some others may tell you money doesn't matter at all, I would disagree, money is important too, because the world revolves around it.



Meh, I'm sure you know all that already, I'll shut up now.
