Don’t make contributions just to get points to level up. The gap between the levels often double, so reaching level 10 can be a real struggle. So I suggest you forget the points and levels and instead focus on helping fellow Maps users and the places on Maps. I have been more motivated be getting photo views rather than points. I had a lot of fun trying to figure out how to make photos that get selected to represent the places as the first photo.
I shared my findings here.
Editing place information is another great activity. Please see project Local Guides clean the Map.
Best of luck.
