I did consider myself lazy as well and that is what I told people, but then I got pills for ADHD and suddenly I wasn't lazy any longer. So yeah, maybe you aren't lazy and you just have ADHD, or maybe you are lazy, I don't know, but it is worth checking it out. It changed my life, if being lazy is a huge problem in your life I'd suggest to look into ADHD more and maybe try get a diagnosis if it seems to fit.
Too be clear, I’m not accusing you of being lazy, but your description seems to apply to me and I consider myself lazy.
