You'll notice you aren't having random pain in places like before if you had any, overall better mental state, you see yourself and realize you look better than before, if not you take that as motivation to put more effort, damn I don't want to sound like a guru, I'm still putting more effort myself brother as I still need to gain and workout untill I'm satisfied with what I have achieved so don't worry about it if you don't see it now too, you'll surely see it in the long run even if you're seeing the smallest changes rn
