When I started mapping the first additions in the OsmaAnd app for Openstreetmap at the end of 2015, I never thought I would make 1 million changes. Entered in OsmAnd and then in Potlach2 (because it was beginner-friendly). Then later iD and other apps. Like Mapcomplete, Streetcomplete or Everydoor. 1
I can only recommend just getting started.
@SeeandMap How did you manage 110000 changes per year? Or nearly exactly 300 changes every day for 9 years 3 months? Quite an achievement!

In winter, instead of watching TV, I sometimes look at new pictures on Wikimedia and link them to OSM. You can usually find even more POIs to map on the photos. But I map over 80% on site and the rest from Wikimedia, Wikidata and maybe 1% from newspapers or newsletters. There is always more to map than I have time for.
