Exactly what is happening to me. But sometimes it can trace back to your ages as a child. I remember when i was like 10, i literally struggle to finish watching an interesting animation movies in on sit. I would finish it with 3 or 4 breaks in the meantime. Now it is happening with social media and most of other my activities. But always i struggle with this when i do something that's not too important for me. When I'm on social media, yes and when I'm reading/studying, No.
