Could anyone tell me what a single word for mental endurance could be… I'm thinking something along the lines of willpower, but less ambiguous, it should fit in the following sentence:

"…has a great desire for improvement and puts a lot of effort in it, but has issues in terms of confidence and (?)"

Thanks!

Your "willpower" really does sound like the most literal definition of "mental endurance", but based on your sample, there are a few ways to go with this.

First is to focus not the abstract concept of mental strength over time, and instead on its results:

...but has issues in terms of confidence and consistency

or

...but has issues in terms of confidence and self-discipline

or just "discipline"... but this might have the connotation that the person as trouble with authority.

If you just mean the person's ability to doggedly stick to it:

...but has issues in terms of confidence and tenacity
