For me, keeping the goals small, simple and gradually building on them helped. I've also changed my mindset to one more focused on discipline than motivation, so the things I've decided I'm going to get done during the day are non-negotiable and I do them regardless of how I feel. The longer I've been doing this the more I notice that feelings are essentially a meme, more often than not completely irrelevant, and also very often based on distorted beliefs about myself, others, and the world. There will be those days where you just don't feel like getting it done and you can't snap out of it, but those are the days where you should do it more than ever, because it's very likely you'll feel really good afterwards, and if you're able to train yourself to be able to smash it on your worst days, you'll be unstoppable. Not a single time has the kike in my head been right about not getting my practice, study or training in for the day being a good idea.
Try this experiment now: pick some kind of self-improvement-oriented activity and do it for 15-30 minutes. Make a note (mental or written) of how you feel before and how you feel after. Do 15 minutes for a week. Then make it 20, or 30, and keep adding to it until you're putting enough into whatever it is to get the results you want. If you don't enjoy it at first, focus, keep at it, the enjoyment and satisfaction will come later. Your aim here is basically to rewire your brain to derive enjoyment from difficult things, so be patient and compassionate with yourself because it will take time. They say it takes a month to solidly establish a habit. You'll find at a certain point that it becomes self-sustaining and you don't have to try as hard as you used to, if at all.
It's good to have blind faith and stubbornness as well. The kikes in our heads can sound very rational in their attempts at dissuasion sometimes, but you should ignore all of it and just do whatever it is you've got to do. Good luck lad, let us know how it goes.
Thank you. Now I've got all my equipment set up I can do some proper recordings for you lads.
