That's why I made a useful chrome extension for myself that redirects me from distracting websites to useful and interesting websites! No more reddit for me, but more Hackernews! No more Instagram, but trends.co. No more YouTube, but more Producthunt.

If that sounds something you want to try, you can add it to your chrome browser for free. Any suggestion would be more than welcome!
