Does anyone ever miss being a kid?

I'm an adult now, but in the 2000s, I remember how much I enjoyed being a kid back then, the cartoons I would watch, the games I would play on my old DS and 3DS, Getting my dog and having hum since 2013... But now I still looking for a job, still focusing on improving my art, trying to make something out of myself... But remembering all that from one video, made me cry... It had me remember how good it was being a kid... Does anyone ever feel like that?
