The first mobile phone I ever owned was a Nokia 1611.

It did have a display, so it was possible to compose text messages and see incoming phone numbers, but that was about it. Still, it had enough features to become a daily companion.

When my history teacher, Sören Lokrantz, caught me texting during his class, he taught me a valuable life lesson. He asked me:

Teacher: “Do you know what made slaves into slaves?”

Me: “Eh …?”

Teacher: “The fact that they were permanently available.

Ever since that day, I try to be mindful of how I adapt to new technologies.

Master technology — never be a slave to it. Be mindful of who's in charge of your life. It should be you! Tweetable
