Procrastination Helmet

YouTube is often a go-to source for rapidly picking up new knowledge because information presented in video format is easily digested.

Unfortunately, YouTube can also be a huge time sink, if used incorrectly.

This extension helps you spend less time watching wasteful videos on YouTube and as a result allows you to concentrate your attention on videos that bring tangible value to your life.

All you need to do is mark videos you visit as either "constructive" or a "time waster". After you have marked a couple of videos the extension will make it harder for you to watch videos which are similar to those you have marked as "time wasters".
