A single word to convey “one who has control of his life/destiny”

I am looking for a word that describes/conveys one who is in control of his/her life, and believes in his own ability to create his own destiny. I am looking for a word that has some poetic/literature tone/connotation to it. Thank you very much.


Solution 1:

"Master" is the closest I can come to one who controls his own destiny with a steady hand.

There are probably several better words without the connotations "master" brings to the table.

"The master worked tirelessly on his tasks, assured they were well conceived"
