Developing will power is one of those "easier said than done" things. At the end of a long day of work, without my phone, I find my ability to focus is shot. Especially since I can't work out like I used to, a few more weeks and I should be able to again. Workouts physically exhaust me but restore my mental focus. There are lots of things that drain people (emotionally, mentally) that leaves them in a similar state, where having the device present is just too strong a temptation and then an hour or more is gone.
