there is no word for word translation for such cliches from one language to another. have a nice day, good job could imply the same thing in different occaions as khaste nabashid. How do you translate' money doesn't grow o trees'? you wouldn't probably say: پول رو درخت رشد نمیکنه that sounds riduculous. however there are alternative expressions with the same meaning like"پول علف خرس نیست

yes good job is correct

سلام تا اونجایی که من میدونم معادلش= Good Job

there is no exact translation word by word but you can say good job , nice job , and more power in your elbow means : khoda ghovat

yes "good job"
