Mentally: It’s actually not that hard, you’re over thinking it. Just do anything else than the thing you don’t want to do. The thing you fall back on is a habit. It is one thing you do over and over, instead of the infinite other things you could otherwise be doing. Recognize in life these fallback habits and do something different. Take the same road to work? Take a different route one day. By breaking habits you open your world to infinite possibilities.
Physically: put your phone in your bedroom or wherever you keep it when you go to sleep. Don’t be in that room till you go to sleep. You break the habit of normally having the phone with you all the time. See what happens when it’s not.
