This year I am reclaiming my attention span away from my iPhone. Lately, I have noticed that while reading or working, I reach for my phone to check email / BlueSky every couple of minutes. I tried to force myself to focus on work / book by using a timer; do not touch the phone until the timer is up. But I think I need a more drastic measure to restore my attention and focus.
So I got myself a "plain" music player so I can read / think / walk in peace and leave my phone at home. ECHO Mini plays everything, is tiny, has 2 audio jacks, has bluetooth, and even shows a tiny cassette tape on its front display!
So now I leave my phone at home and bring a music player (which can fit lots of MP3/OGG/M4A/FLAC files), some headphones, and a regular watch to know the time. Now I can think, read, and work in peace.
