Well, I know a number of people like Tim in real life, and while they are great people, they can't hold long term relationships or be "close friends", because they are so focused on self-improvement/fulfillment that they just don't have the time for other people. They end up being more "James is in town - we should definitely head to the pub" friends more so than "James - I'm having a really tough time and I just need someone to talk too" friend.
I'm sorry you guys think this is trolling - but seriously, how does one dedicate their life to learning a new skill for three months straight when they have a family or close friends who depend on them? Its honestly something I struggle with when looking for guidance from guys like Tim.
