For this reason, I have this kind of conversation almost daily with people asking for help in studying or just ways to "find motivation", etc. I always ask them "Why are you learning Japanese?".
The amount of answers I get that revolve around the idea of "I want to get better at it" always amaze me. I'm the kind of person that just does things because I want to have fun. I learned Japanese because I enjoy doing stuff in Japanese. I never cared about learning Japanese, it just happened that doing so made it fun for me in the process. And yet there's people out there whose entire goal of learning Japanese is to "learn Japanese"... I will personally never understand that mentality myself, it's very puzzling.
