For many people, live events are away out of their comfort zone. For many reasons, they do not feel comfortable in networking and having conversations with strangers. But as you should know, if you put yourself in a position where you have to stretch outside your comfort zone, then you are forced to expand your consciousness.
If for only one reason you should join a live event or conference is to move out of your comfort zone. You can only grow if you are willing to feel awkward and uncomfortable when you try something new. You will get inspired by others and more motivated to accelerate your activities.
