I will make it easy for myself... I use my mobile phone for one reason, and one reason alone - convenience. I need to remember this

If it is not convenient... And if it won't help me I just won't use it. - Does it simplify my life when I need it simplified? - Will it save me time?
- Will it make me money?
- Can I go home sooner if I use it?
- Can I avoid a backlog at work?
- Will it help keep my 4-year old entertained while we wait for something neither one of us wants to wait for? -Usually a Doctor or my wife at the store...;)
- Will it save me a trip somewhere?
- Can it help put a smile on my customer's face?
- Etc
