I got rid of my cellphone because no one calling me was anyone I wanted to talk to.
I used to be a financial/investment advisor, and those calling were mostly financial service wholesalers (insurance and annuities) and other commercial calls. Whenever I felt a vibration in my jacket's breast pocket, my stress levels would soar, and more than half the time it was imagined. Now I feel free, plus I'm probably saving $100 a month.
I'm now a programmer at a bank, and my wife can get me at my desk at work. I got a small tablet (a Nexus 7) with a data plan (attached to my wife's phone plan so it's cheap!), and I paid $20 to switch my phone number to Google Voice. Now when someone calls, they can leave voice-mail or text me, and it shows up in my gmail on my tablet. I added a Zagg hard-shell bluetooth keyboard and it's like I'm carrying around a little laptop.
I feel like it's an awesome change that has really improved my quality of life. I love to brag about making the change, in hopes that others might be inspired to follow suit, thanks for the opportunity.
