Writing takes time. Between 2008's Paper Towns and 2012's The Fault In Our Stars there was another book titled The Sequel that ended up being scrapped entirely. Different writers write at different speeds; it's an art form that doesn't generally benefit from being rushed. That being said, it stills sucks having to wait such a long time for a new John Green book. Sure, Green could probably write something profound and wise about what the process of waiting really means - but until then, fans are going to remain impatient. Just finish your next book already, John!
