From my experience so far and from all that I've read around Kickstarters, marketing and networking your project is paramount to success but… I actually think it's equally as important to manage yourself too. Yes, you want to push your campaign while it's live, offer info before, and support it after, but I know there's TONS of projects that don't make it. Make sure you're not willing to give up, and always handle yourself professionally throughout the project, no matter how well it does
