I ordered an iPhone mostly because I needed something that would actually work in Chicago after I graduate but also mostly because I was sick of everyone else being able to check their e-mails everywhere.
Now, I feel a little guilty, especially after reading all of those articles about how our brains never get a second to process all of the information we feed them. We do not give them a break to contemplate.
My rules for smartphone usage:
no walking and reading the news.
no walking and sending e-mails.
no walking and playing traffic rush.
it is okay to stare outside the window on the orange line and not at a screen.
it is okay to leave an e-mail hanging for some hours.
I hope I don't overwork my brain.
