Did Luke reach his full potential?

Did he reach his potential and just choose not to use his full power, or did he still have room to grow?

No one knows. No one ever will know.

Just about everyone still had room to grow. Only real exceptions are folks like Dorsk-81, who literally harnessed so much power he fried himself.

Considering how he was molested by Abeloth, f-uck no.

No one ever reaches his "full potential" in any endeavor.

Wasn't Rockefeller capable of earning one million dollars more than what he earned? Couldn't have Alexander won one more battle? Didn't Michael Jackson have one more chart topping single in him? Mike Tyson one more fight?

You never reach full potential, but you do reach the point of diminishing returns

Nah, he could have been much better.

Luke could only reach his full potential by listening to Oasis's 'Champagne Supernova': https://youtu.be/tI-5uv4wryI

Joking aside, I think no Jedi reaches their full potential because of the temptation of abusing its [The Force] power which could lead to the fall of the dark side
