a person who acts and gets things done;
"he's a principal actor in this affair"
"when you want something done get a doer"
"he's a miracle worker"
- Great boaster, little doer.
- It's better for the doer to undo what he has done.
- He is a doer, not a talker.
- She's a doer, not just a thinker or a talker.
Piebald was a good doer;..that pony's head would go down to the food through it all.出自： F. D. Davison
