+1, also recommend StreetComplete alongside it. Makes it easy to add data to OSM, in many cases (parks, etc) this data can be made extremely detailed.
For instance, my first use case was adding house numbers around my neighborhood to OSM, because I couldn’t search for my address on Organic Maps
Productivity is completely unrelated to success imo. The only thing that matters is that you’re happy with yourself and your life, maybe productivity is not what brings you joy?
Those activities are just as valid as a productive activity, especially if they make you happier. Being productive is great, but I feel productive activities should never take precedence over non-productive ones simply because they’re productive. Do what you have to do, but never sacrifice your own happiness at the altar of forward progress.
