You're going to hear lots of stories about endless days, government bureaucracy, unexpected costs, trouble getting distribution/sales. Don't let the horror stories scare you away but do take note of all the troubles others have faced. Would I have actually pulled the trigger on this business if I knew all the obstacles I'd have to clear to get it up and running? I don't know actually... That said, I'm glad I was a bit naive and moved forward. Take note of the troubles of others and include contingencies in your plan in the event you run into similar walls.
