After being addicted to the point of wasting 1-2 hours on the site every day (one time I even spent over 4 hours obsessively organizing my queue), I finally deleted my tumblr. It feels good. I've also been facebook-free for about a week now. The only sites I will be visiting frequently from now on are this one, which is extremely helpful, and a few others that are productive/educational. Hopefully now that I've eliminated a lot of time wasters and negative spaces I will be able to be more productive and start turning my life around.
