Block distractions by making websites a lot less appealing - turning them into black and white
Black Distractions extension will allow you to turn any website to black and white in order to make them less appealing, and attempt to "block distractions".
You can set timers for your work hours so you can stay productive every day!
Many websites utilize psychology techniques in order to get us to spend more time on their website. e.g: Bright appealing colors, notifications, etc.
By simply turning off the colors on websites, it allows our cravings to remain in our control.
You will spend less time holding yourself back from visiting certain sites, which will in turn use less will power thus providing you with the same energy to be focused onto other tasks.
Remember that willpower draws on a limited stock of energy.
Be less tempted = More productivity.
Give Black Distractions a try for a few days and see the changes for yourself.
