get into city management, and mess around with moving your city population from working one tile to the next. That way you learn to balance your food - hammer - gold production in a city. On higher levels you HAVE to know how to do this, trust me on that.![]()
Nice to hear back.

For microing things an old Civ mantra.
Try to never work a tile in a city which does not have an improvement on it. It's not an efficient use of a happy face (because each population costs a happy face).
This means making enough workers and keeping them busy selecting which tiles to improve. Or if you just have bad land which is not worth improving, put a citizen as a specialist instead.
