Yep, definitely what makes you happy is the most important thing. If you do become an actress (and I wish you luck with it), even if your mum isn't initially happy, she'll end up seeing how happy it makes you and you being happy hopefully means she will be too.

Cool, I'm on Facebook and MSN as maskenball@live.fr - unfortunately stupid Facebook won't accept that my legal name does spell Alexxandra, and automatically rejects each request I make to spell it correctly, so I'm stuck there as Alexandra. One day, they'll answer my numerous requests to please have it changed!
