Very hard to imagine running my business without my smartphone, so I’d say it’s been very beneficial to me. And if I’m being honest, do I use my phone too much? Yes, but not during dinners or when with the family.
However, I will add, that the way I use my phone is similar to the way I consume other media. I read newspapers, magazines, and books, cover to cover. I get sucked into reading something and I can’t stop until the end. The internet is endless but I do have my limitations to ensure that my consumption is not endless.
A better question for me would be - if someone could guarantee the same profit in my business and quality of life without a smartphone, would I still do it? Likely not, because I really enjoy learning new things that much.
