“Digital vegetables can be a healthy use of screens (researching a term paper), while digital candy (Minecraft, Candy Crush) are hyperarousing and dopamine-activating digital stimulants without any ostensible 'health benefit'.”

― Nicholas Kardaras, Glow Kids: How Screen Addiction Is Hijacking Our Kids -- And How to Break the Trance

Attempt to make most of your technology "digital vegetables" over "digital candy" with strategies like these:

Label various devices for "digital vegetable" use - Label an old smartphone a "music player," place a laptop in the common area of your home with a print out of passwords for learning websites, or leaving writing prompts next to it to prompt creative writing.

Give your phone a home - Create a spot in your home to mimic how phones used to hang on walls. It also serves as a reminder that a smartphones main purpose is for communication as opposed to escape. 

Place your phone in your shoes - This can serve as a good reminder to use your wind-down time waking or jogging with some music instead of simply sitting and scrolling.
