Here's advice I would give to people going into a creative field now:
1. Be persistent. No matter how talented you start out, the playing field is always measured by those who keep going. That in itself, is a valuable skill.
2. Believe in yourself. If you don't, who the hell will? Trust your gut, not a one-size-fits-all program. You know what your experiences are, and when you can present that confidently, people will listen. There are many times through my school life that I knew what I wanted to do, and however uncomfortable it was not to be running with the pack, I would step out of my comfort zone and meet the most amazing people, gain valuable experience, and learn a whole helluva lot more than if I stayed on the beaten path. And that makes you even more marketable.
3. Choosing a creative major or path is not useless. At least not inherently so - but just like any other major, so much of your success after school is based on you. You have to have that ambition, baby.
4. Do internships while you're in school. I've done six. Many were unpaid, including one where I lived with my parents for the summer and commuted 3 hours just to read a script slush pile. A few were paid (I should note, paying ones were all graphic design internships). Here's a secret: people are especially nice and willing to help you if you are offering your time for free. Especially the ones who are worth your time. Also, early on I was too shy to make the most of my internships. Ask lots of questions, engage, act like you're in for the long haul because you never know what rabbit hole you'll fall down. Talk to everyone.
Also, the in school part is key, because after you have your degree is NOT the time to be doing a 2 year long unpaid internship (see: HBO's Girls). That is the time to get off the bank of mom & dad.
5. Sometimes all the doors are closed just so you can open one that leads you down the perfect road. Yeah, I just quoted Katy Perry. Rejection, disappointments, closed doors will always hurt. But that never means the end. In fact, it usually leads you somewhere even better than you could have imagined.
