I've met a lot of people in the industry, and one is my best friend, so if this came up with anyone in my life (friend or lover) I would tell them what I've seen good and bad. IMHO it's a tough as hell job that if you don't need don't do, if you do need figure out a plan and try to stick with it as well as possible. If it was a lover I'd look for other options but respect her decision.
