My Year of Golf and Relaxation (part 1)

Malt Liquidity • 12 implied HN points • 21 Mar 26

  3. Golf offers rare, accessible flow: a scenic walk, social time, and a restorative outlet from an always-on information life. That mental benefit depends on mindset—only the player can "spoil the walk".

10 Things People Don't Realize About Scrum

Ageling on Agile • 119 implied HN points • 20 Oct 24
