I couldn't agree more!
When I think back to who my professional role models are, and who I try to emulate in my current position, a few come to mind. But one in particular stands out and distraction, cell phones, etc is the #1 reason why. The first one on one meeting I had with him I realized afterwards, he NEVER checked his phone, glanced at his email etc while we met. He gave me 100% of his attention. Sounds simple enough, but the reality is that never happens. So now I use it in my every day practice at work and not only am I more productive, but I've built stronger teams due to the energy and focus I'm able to put into my time with my direct reports.

One of those reports is struggling in a big way with time management. We have a meeting next week and this will be my next suggestion to her. Airplane mode, completely off, whatever it is you need to stop the "quick" glances, but stop. Although it feels like it's just a second or two to read a social media comment or notification, the distraction continues much longer. A few seconds longer to tell somebody about it, a minute or two to gather yourself and get back to what you were working on before it. Another second or two later when you remember the comment, etc. It carries on and extends to many loss of useful hours in a day; whether personal or professional.

It's a great tool but it need to be managed and expectations for ourselves set.

Fantastic post, thank you!
