For general laziness, in the order of importance: fix sleep (consistent wake up time), exercise, diet (cut out sugar and junk food like potato chips and ice cream, soda etc), vitamin D, blood tests, regulate stress, keep track of coffee, meditate, reduce alcohol, take breaks from social media, porn, addictive games, binge watching etc. Read physical books. Go out in nature without phones.

Such things can help immensely with vague laziness. Don't overthink it, there is no magic quick fix and it's not just about this one weird self help trick to fix your mindset. We tend to forget how much we are biological animals on the inside and the animal needs to be kept well.

Start with waking up at the same time and winding down in the evening early enough to sleep enough. It's much easier to get a grip on such concrete things as waking up at a particular time (or not eating added sugar) vs starting the big vague project, staring at the empty console. Once your routine is set up you will find you have more willingness to face and take on difficult tasks of many sorts.
