I have the tunnel vision. I know that I have an telco at 14:00 this day. But if a team mate asks me for help at 13:45, then I walk to his desk and then it is likely that I forget the telco.
An alarm app on my mobile phone does not help, since I usually don't carry my mobile phone with me if I go to the room of a team mate.
I don't want to wear these huge "smart" watches which need to be charged (battery) often.
A small watch or other device would be ok. But I want to charge the device only once a week.
Or is there an other live hack which could help me having the tunnel vision?
