thanks for playing! each activity that trains a skill has a cap - you can't become the strongest man in the world just by doing pushups in your room, and you can't become a master blacksmith just by making one or two things at a local forge. Right now the cap on lumberjacking is 70; the new version of the game I'll be releasing soon already has a lot of added messages letting you know when you've reached the skill cap from a particular training method.
