Lack of support and confidence is one of the biggest difficulties I've had to face so far. For my videos, for my podcast... I somehow need some confirmation from people I care about no matter what I do. The problem is that it means my happiness AND my success depend on them. That's bad. As much as you love your friends and family, you cannot let them steer your life... Plus, if you start believing in yourself, if you are proud of your creation, your job, they will start to think so too. They will start following you. So don't act like they owe you this.
