Ask HN: How to quit social media?

I spend almost 3 to 4 hours on reading news, facebook posts, tweets, watching videos. I want to get rid of these. Right now,I have started asking myself a question before any task - how would it improve my life or support me finacially? If answer is positive, i do that task. But I think that is not the perfect way to handle this situation. So how do you handle internet distractions? How to get rid of these bad habits?
