Ask HN: What would be a cool goal setting tool?

Hey guys, I am currently looking into creating a tool to track goals. Those could be either life goals, projects or single tasks. Maybe some of you guys already use things like trello etc., or just the good old fashioned paper.

To get a rough idea what i'm thinking of, see this: https://www.dropbox.com/s/i5t0ei7iusk95i8/Screenshot%202015-03-20%2019.11.59.png

Would you use something like this?

What features do you think it needs to have?
