With so many books out there someone who wants to get into reading may not know where to start and others may not want to start at all for the commitment in time that it takes (which is likely most people).
So I share advice from Naval Ravikant. Start by reading what you enjoy. Any topic, as long as you have a direct interest in it. Fiction or non-fiction. Read something on a topic you enjoy and then you'll enjoy reading. Once you come to enjoy reading you'll no longer be concerned with the time it takes and you'll also begin to branch out into other types of stories and topics.
