What if you unsubscribed from everything for a day?
How much time would you get back?
I know it sounds impossible but there was a time when you were never subscribed to anything and you could just be you.
If a day is too long and you get withdrawal syndromes just thinking about it, then try it for an hour, or even 30 minutes. By the way if the idea of unsubscribing does cause you anxiety then perhaps that should tell you something.
Go ahead and unsubscribe, I promise you the world will still go on and everyone vying for your attention will still be there when you re-subscribe.
