Tumblr started as just another thing that I did with my friends. And since it started, friends have come and gone, and this blog has been used for multiple purposes.
It was once used for a story I was working on, then as a audio/video journal, then as a kickstarter for my youtube channel.
Now, I'm keeping a dream journal in the hope that I can achieve a state of lucid dreaming.
Occasionally I wonder why I do all these things. I can't give a more elaborate answer than "It's just me"
