Ichiro Suzuki on his bat case:
In Japan we take care of our instruments, our bats and our gloves….We take care of them well because these things are very important.
Most of us take good care of our work tools as well, including laptops, Smartphones, and tablets. You may even keep a special pen and paper clean, like I do with my Kaweco sport pen and Moleskine.
Clean tools create a clean mind. We use our tools constantly to express ourselves. They should be protected at all times since without them, we’re virtually useless and unproductive.
