Daniel Pink shows us in his book, A whole New Mind, different ways to conform to the conceptual age that is approaching us. Pink tells us that in this conceptual age we will have to beat out Asia and automation for high paying jobs. One way he explains to beat these other job seekers in Asia and through automation is to start designing things that would be useful around you, or just redesigning things that are already around you. So Pink gives the suggestion to carry around a design notebook, and whenever you find something to design, redesign, or take a note on something that sound good or bad to you, the notebook is right there and ready for your input.
I took Pink's advice and carried around a notebook for a week. When I started looking, there where tons of things that could use improvement! I redesigned probably 10 things just when I was sitting in my living room, and the more I went, the easier it was to point out flaws.
One of my designs was to save the battery on cell phones, ipods, and laptops. I've noticed that people often leave these things on their chargers, and it burns out their battery, making them less efficient. So I came up with an idea of a charger that stops charging the phone once its 100% charged, and lets it run out of battery completely, or if you want, you can have a desired percent of battery power left in the appliance, then it will start recharging.
I think if everyone carried around a design notebook, the world would move much faster into the conceptual age. It would promote creativity and efficiency in our appliances, it could definitely benefit all!
