The best tool to not get distracted!
This tool helps you not to get distracted as it blocks any apps and websites taht you want. For example, you can block YouTube if you find it distracting. The best part is that you can put it on “locked mode” and you will not be able to disable it under any circumstances system settings and task manager will be disabled so you won’t be able to force quit it either. This is really the ultimate solution to getting distracted. Here are some pictures of the UI:
Session customizer (you have the option to make it reccurent if there are given times that you want blocked) 
Entirley customizable blocklists with available presets) 
Locked Mode and Focus mode (Focus mode plays backround noise)
