I've been in this scene for a little bit, been watching kids since high school start up t-shirt labels, production companies, event coordination teams, and while i admire the hustle, i have no respect for the shoddy approach that my peers have to their crafts.
What makes a truly successful venture is an attention to detail and a damn good creative direction, whether you're in an arty field or not. Put some elbow grease into what you want to pay your bills, if you don't, you'll end up having to work for someone who did.
If there is anything that can push your dreams into reality, it's dedication, and too few of us these days understand the importance of focusing all of your energy into what you want to build. Hell, we're all just a little too concerned with making it sound like we're obsessed with dedication. Try the twittersphere in JHB on any given morning, drenched in the supposed sweat of tweets preaching the gospel of hard work, of dedication, of inspiration, and of future success. But comrades, there's no use in preaching success when you haven't yet overcome the baby steps.
Want to party while you're young? Then be prepared to work yourself to the bone when you're older.
