Both, based on need I'd say. In SX its mindfulness principle again, and I can expand the sentence above with "plan, when you need to plan".
Plans are certainly needed at different granularity and scope, for different purpose, and likely having relationships to each other too.
Mindfulness is one thing, but Sustainability core principle is about finding the right balance of when to do what and when. You must plan to anticipate your Risks timely, for instance.
Finally there's Playfulness core principle, which is the most powerful, but also only truly comes into play (pun intended) when the other core principles are addressed to a minimal extent.
Here is the freedom to be creative, to experiment, to be flexible and versatile, to work at your own leisure, to just have fun, etc. This all relates to the Joyful creation SX formula, and the stimulation of intrinsic motivation to participate in the commons, find places where you fit, and foster cohesion.
