You can't have 'no idea as to why'. It's your business and you need to know this. Also, the issue seems to be more with your lack of work ethic and less to do with the business itself. So i think you should think about that. Any business gets monotonous in the long-run once the excitement wears off, so I also think you should stop thinking that the business needs to be 'fun'. As long as you don't hate it and you're doing well, you should continue the business.
