Your own goals and days left, on every new tab. Ads work because you see them constantly at the moments you're not focused, like opening a new tab. This replaces your new tab page with your own goals and deadlines, so the only thing advertised to you is what you actually want to get done. Goals are stored in Chrome's own sync storage. Nothing is sent anywhere else. Open source (MIT): https://github.com/rsktaker/advertise-to-yourself
