I think there's a lot projected on beautiful women, period. At least, maybe this is just my fear, but I do sometimes feel dismissed before I've even been allowed to participate. I have moments of feeling really wounded. But I am pretty optimistic, and I do enjoy a lot of my life.
Pick up a camera. Shoot something. No matter how small, no matter how cheesy, no matter whether your friends and your sister star in it. Put your name on it as director. Now you're a director. Everything after that you're just negotiating your budget and your fee.
Mistakes are almost always of a sacred nature. Never try to correct them. On the contrary: rationalize them, understand them thoroughly. After that, it will be possible for you to sublimate them.
