How does one choose a career?

Same old story: you go to college, take some general education classes but in the end you don't know what you want to do as a career. What is more important: to do something you like but you already know that your chances of a nice salary will be always scanty or to do something you KINDA like but you know that your chances of financial success are quite high (despite the economy)?

Here's my "friend"'s dilemma: she is good at writing (or THINK she is); she has an analytical mind and likes paperwork as well. She is curious and loves almost everything, from science and technology to arts, film, music and fiction writing. She is not as good at math, but she is quite good at biology and chemistry (and she likes both). She likes research and the academic world. She is super organized and very good with her deadlines. She also likes sports and nutrition and fitness. She is upbeat and hyperactive. She loves politics but hates getting anxious and nervous. She doesn't like arguing. She is good at preparing arguments when she has the time to analyze the situation. She is good at details and picking up on loopholes. You can give your paperwork for her to review. She has good grammar but bad mathematical logic. She doesn't like blood (she can't be a doctor).

Here's her "background": she has worked in a newspaper. She liked it. She learned about how scanty the pay is for journalists. She learned that journalism is a career you undertake out of love only, because the hours are long, vacations are short, and the pay is even shorter, when you are lucky enough to have a job (because editorials are shrinking).

Everybody tells her she would make a good lawyer. But she doesn't know if she will love Law. Or if she will even like it. She thinks she might make a good lawyer, too. She thinks she might like Law. But she is not sure. She has been to college 4 times now and never graduated because she never knows what she wants to do. For most of her life, she wanted to be a filmmaker and an actress/writer. But she realized she doesn't have any talent to act, and she is not driven enough to be a filmmaker. But she believes she is a good writer and has some good ideas and writes with her heart. But she can't finish anything. She just can't finish any of her fiction works. She doesn't want to do it wrong again.

So she is thinking about Law. Her biggest concern is to be happy with her profession and be able to have a comfortable life. She doesn't want to struggle every month to make ends meet, for the rest of her life. But she doesn't want to sacrifice happiness for money. She wants to be happy.

How is my friend going to solve her life puzzle???

Thanks for any ideas or suggestions (please don't send criticism - she is already super hyper critical of herself...).

PS: Telling her to play the lottery doesn't count. She has already tried this one...lol
