Joy, rage, sadness, fear, I get all these can be creative fuels with unique uses. But what about tiredness and disinterest? I've never been able to get them to work in any engine so to speak. Have you ever harnessed em?
no, but if you are tired you can sleep, and if you are 'disinterested' you should try to specify what you are disinterested in. then get away from that thing and find what you are interested in
