When working in a team, we usually forget to be humans and focus on the work instead. But did you know it can be so much fun to improve as a team? I just came back from a week-long team retreat where we had team activities, team games, and sessions and discussions about how to grow as a team.

We figured out how much we value diversity, we realized how different the English language and its words are perceived by people from different countries, and we’ve seen short talks on various topics like work-life-balance but also on technical stuff like Docker or intercepting any computer’s traffic with a Raspberry Zero. So if you have the chance to work in a team, use the opportunity and exchange views and share information with your co-workers. Work is part of your life, so why not make it a lovely part?

Work & Life

  • With tons of productivity articles out there, it’s easy to feel overwhelmed or even bad about how you get work done. But each one of us is an individual, and, thus, productivity is not only a subjective matter but also has a personality.

Going beyond…

  • Ben Sauer questions the use of digital media for everything and asks himself if embracing paper to share information in a team is a better idea.

And with that, I’ll close for this week. If you like what I write each week, please support me with a donation or share this resource with other people. You can learn more about the costs of the project here. It’s available via email, RSS and online.
