Proper translation for 수고했어요 정말 고생했어요
A friend of mine wants 수고했어요 정말 고생했어요 as a tattoo and she asked me to check it for her. She said the proper translation should be "You did a good job today, you worked so hard" and it does seem to be that, but I want to check with native speakers. She was also wondering where the comma would go, but I'm unsure if it belongs before or after 정말

Question

Answer

yes, she is right N we often use it. 
정말 is adverb, so you can put anywhere on purpose. 
, is... where do you but comma in your language? i think it doesn't have any difference with your language.

4.approximate number.

5. to avoid repeat same mentions

6. after the answer or name calling.

7. to avoid confusion.
