Kylo kept a routine. He would wake up and meditate, focusing on Rey, her image, the way she made him feel, her connection to the force. And then he would set her free. And then he would work out, if Fey had a lesson for him he'd follow her, if not he's just explore. Then at the end of the day he would meditate on his anger, shaping it and molding the image like she had taught and then expeling it. As the time went on it grew easier to fall into the routine. He did what Fey told him, didn't think much beyond what was right in front of him, just followed the steps.
When he thought he'd explored the whole planet he found a new path and decided to traverse it. After walking along a winding path he found he was lost. The rocks that had led him there looked the same as the rocks in front of him. He didn't know where he was or how to get back. He kept going, and when night fell he stopped and did his usual meditation.
