Deleted YouTube, Facebook, Instagram and LinkedIn from my iPhone and iPad this morning.

Edit (Jan 17): re-downloaded Instragram two days later and set a short app limit (experimenting with seven minutes) using Apple's Screen Time feature. Responding to direct messages burns through my daily limit, but it keeps me hyper-focused when I am in the app. Sometimes I will draft a message outside Instagram and then copy it in when I'm ready to send. I am spending 30-45 minutes less each day on Instagram than I was just a week ago.
