Stay focused on what matters. Intercept distracting sites and redirect your energy to meaningful projects. Traction is a tool that helps you spend your time on the projects that matter to you, not on distracting websites. But this is not a blocking tool, Traction simply asks you if you'd rather spend time on a project that's important to you than going to a website that is a time suck for you. Both of which are defined by you when you set-up the extension.
