What Simon Sinek teaches (and what to take from it)
Start with why
Sinek argues that people follow a purpose before they follow a product or plan. This week, write one sentence about why your current work matters to you, then check your calendar against it.
Play the infinite game
In The Infinite Game he contrasts one-off wins with building something that lasts. Over the next few days, name one decision where you traded a short-term win for a long-term gain, or could.
Build trust before pressure
Leaders Eat Last is about teams where people feel safe. Today, ask one teammate or friend what would make working with you easier, and listen without defending.
Find your why with others
Find Your Why is a guided exercise done with a partner. Before the weekend, tell someone about a time you felt proud and ask them what they heard in it.
