Well I define creative block as some stress preventing us from creating stuff, and in this sense, I'd say it's a real, but I don't think it should be seen as a bad thing necessarily and instead be seen as neutral: just some stress preventing us from creating stuff. Then it's about figuring why that is, and the reason can genuinely be a good thing! Like "Maybe I really shouldn't be doing creative work at this moment because I have this other important thing to do", but i feel like some people shrug this logic off like "No, my room is a mess, and I have a lot homework due in 2 days, but im just gonna go ahead and draw a castle..." Like no, take care of that other stuff then come back and have fun later. Though I do very much agree that if someone hasn't tried exploring other hobbies, there's a good chance doing that can make their life a lot richer. Sometimes it's just loneliness that kills motivation too. It's hard to know exactly where the stress is coming from at first, but worth looking into instead of sweeping it under the rug.
