Mark 1:38-39

He replied, “Let us go elsewhere, into the surrounding villages, so that I can preach there too. For that is what I came out here to do.” So he went into all of Galilee preaching in their synagogues and casting out demons.

Jesus is in Capernaum, and is awake early in the morning to go by Himself to pray. For at least the second half of the previous day, Jesus was receiving all sick and demon-possessed people. He healed many diseases and drove out many demons. Now as Jesus is praying by Himself, Simon comes to find Him. Simon tells Jesus that "everyone" is looking for Him. Focused on His mission, and not distracted by the lure of popularity, Jesus takes this as a cue to continue to other towns and preach.
