Great employees are made up of two foundational elements: enthusiasm and teachability.
The former denotes a passionate individual, while the latter is one who wants to develop and progress, who is hungry to learn, and who evidences the trait of humility.
If you can find an individual with these two traits as well as highly developed skills, then you’re on to a winner. And, even if the skill levels are less than required, their rise to skill mastery will be much faster if they already have these two foundational traits.
