HN is one of the places online that is NOT a wast of time. It is full of useful informations. After using internet since mid 90's, and being one of first people that got the first gen iPhone, now days I try to NOT use smart phone or internet unless I need to. This is has significantly improved my life quality. Having more fun, I focus on the people around me and the 3d reality more. Then when I was using a lot of smart phone. Of course that is not the only thing, I had to do however it is a VERY good starting point. Highly recommend everyone who owns smart phone to try using it only in airplane mode.
