Oh, where to start!? There are so many hurdles and they keep changing as you grow and evolve. From my own personal experience, I'd say, always have your wits about you and be very careful who you trust. Don't believe everything people say and promise - many of them will let you down. Also, keep your eye on the ball, watch the competition to position yourself just right - some may steal your ideas but don't let that faze you because you must be doing something right. If you don't know people in high places, you may struggle to get a foot in and have doors slammed in your face - if you believe in your hustle and have a passion for it, don't let it slow your roll. Keep it moving because one day you'll get a breakthrough.
