Goals are a way for you and your patrons to track your progress on Patreon. An example of a great first goal could be, earn enough to buy new camera equipment! This is a great way to encourage your community to pledge to you– Allowing your patrons to be involved on your journey as a creator, helping you reach new milestones!
Goals live on the overview section of your creator page. If you have multiple goals set up, once you reach your first goal amount, it will complete and the next goal will appear. 
You and your patrons can select view all to see a summary of your goals, including ones you've already reached! 
How Many Goals Should I Have?
You can have as many goals as you'd like! However, if you're just getting started on Patreon, we suggest starting out with one or two. Once you've completed those, you can add more!
Remember, you can always add/edit your goals at any time!
