It says "one day I might rule the world".

As for a word for a person who is a "doer", gets things done - I can only offer you some modern Hebrew slang :

שאקל - sha-kel

תותח - to-taCH (a canon)

I wrote these two in male form, if you want to change it into female form - add ית (yit) to the end of each, תותחית, שאקלית.

One more option comes to mind is borrowed from Yiddish, and only refferes to a female :

בלעבוסטה / בלבוסטה (ba-la-boosta) which means "a house owner", as in a house wife that do, know, and control all.
