It might sound cliched but I think up the best ideas for my stories when I'm in the toilet...no idea why, but that's how it works. What about you guys, where's your 'inspirational zone'?
Usually when I get the best ideas when I'm intoxicated or under the influence. Theres also the times where I'm put under a lot of pressure and thoughts race to me because I get a slight adrenaline rush. I also get some pretty good ideas while I'm playing video games.
When I'm going for a long road-trip, just staring out the window-side... that's when my ideas really starts to catch fire, haha But yeah, whenever I have time to think I suppose.
