    I've been thinking a lot about what motivates and excites me when it comes to "work." Yes, that list is long and wide but I think the key thoughts here are: happiness, freedom to execute a vision, impact potential, and ability to pay the bills. I found these blog posts inspirational.

    While debugging an Android app I was writing, I noticed in the adb logs that my phone was performing a "check-in" to a google.com URL. A quick Google search yielded the following blog post. Apparently Google sends your Android phone's IMEI, Wifi MAC, Google account ID, and model to their servers every so often in the form of a "check-in."

    From Building a Thinking Room:

    "Test-takers in the red environments, were much better at skills that required accuracy and attention to detail, such as catching spelling mistakes or keeping random numbers in short-term memory."

    "Though people in the blue group performed worse on short-term memory tasks, they did far better on tasks requiring some imagination, such as coming up with creative uses for a brick or designing a children's toy. In fact, subjects in the blue environment generated twice as many "creative outputs" as subjects in the red one."

    "She demonstrated that, when people are in a high-ceilinged room, they're significantly better at seeing the connections between seemingly unrelated subjects."

    "If we're performing a job that requires accuracy and focus (say, copy editing a manuscript), we should seek out confined spaces with a red color scheme. But for tasks that require a little bit of creativity, we seem to benefit from high ceilings, lots of windows and bright blue walls that match the sky."
