If you're familiar with the world of social campaigns, then you know these things don't just run themselves.
Campaigns require effort, like anything else worth doing in life. Make sure you are constantly asking yourself what else you can be doing to help your campaign achieve it's goal.
You should:
Have an effective promotion strategy.
In addition to your personal outreach to friends and family, you should also consider drafting an outreach email about your campaign to send to social media communities and bloggers
Get the word out every day.
Don't just make one announcement and leave it there. Promote your campaign constantly, and don't forget to give a big push pre-launch and for the final throws of your campaign. Most people are inclined to back a campaign the day it launches (so they don't forget) or right as it finishes (so they don't miss the deadline).
Keep your backers updated.
And encourage them to help you share promote the campaign!
Don’t assume that, once the project is online, the funding will take care of itself.
Keep working and keep your eye on the bigger picture.
