When it all boils down, friends are just a waste of time, really. People don't seem to understand that if someone is friends with you, it's because they feel good in some way as a result of being friends with you. It's why humor is a tool that is used by many people in order to maintain friendships - hence why all the popular social kings are usually comedians - making fun out of people is a common occurrence. . The best way to check if this is true, is to ask yourself, would you really want to be friends with a deeply miserable, depressed and depressing person, that gives off bad vibes? No, of course you wouldn't. I'm not saying you're like this, but for many people this is the case - they don't even know it, and go through life wondering why they have no friends. Friends will not really get you anywhere
You will spend your life making and receiving jokes, laughing at people, sitting in coffee shops, saying pointless phrases like "how are you", "fine, you?", "yeah not too bad thanks", and following other pointless social conventions that are responsible primarily for our civilization and gene reproduction. But in my eyes, this is wasteful of time that could be spent by doing meaningful things - like actually helping people, inspiring people, changing the world positively (in some remote way, not just for yourself), etc. You still do those latter things for selfish reasons (helping people makes you feel good), but it's actually meaningful (in my opinion, at least).
