I don't consider the term Otaku as something that only applies to anime viewers. In my case it has a lot of different aspects to it, and I still don't really consider myself an Otaku because I feel like I'm taking something away from diehard otakus.
My life as an "otaku" hmm. I dont know what to say there because to me, sadly, it's secondary. My life is kinda difficult and hard, so I dont have the time to sit back and go "ahhh this is the life, I feel good about this". Instead I sit down to watch anime and I am interrupted 5 minutes later by another dramatic debacle around here. Or I'm doing countless hours of homework. Or listening to another complication that has arisen.
So if I DO have a life as an otaku... it'd be my few seconds or items of sanctuary. The moments I get to watch anime right before bed, the moments I get to watch a k-drama if I have a day off and its a lucky quiet day, the moments where I listen to music on repeat on the bus, the fraction of seconds when I can look at a website online and see a plushie I really like and wish I could have but then I look at the price and say "well. at least I got to look at it. I hope whoever gets it will treasure it a lot.". and so on. I don't have the luxury of calling myself an otaku. I have the constant responsibility of moving forward and I can't even stop to enjoy the weather. Half the time I don't even know what colour the sky is at the moment.
