Ironically, the first time that came to my mind was Hive. I do enjoy spending time writing and engaging people, and learning new stuff, on Hive but I have learnt over time that I needed to strike a balance with other aspects of life as well. For example, if I were to stay up too late and don't get sufficient sleep/rest, it would affect my health/mind at work the next day, or if I were to forgo my exercise sessions just to read a few more posts here, it's neither healthy nor good for my weight as well. Over time, it's really about finding a balance and accept that there's only 24 hours a day and every hobby/activity has its place in one's life.
