If you think arming teachers is the solution to gun violence, I bet your track record as a manager, especially a hiring manager, leaves much to be desired. You are probably the kind of manager who treats employees as interchangeable pawns. I suspect you hand employees new responsibilities just because they are handy and/or available. I am quite certain you expect everyone to adapt to new tools instantly. I bet you can’t figure out why your employees aren’t happy and thriving.

The number one factor affecting success on the job is fit. Fit is the extent to which the needs of the job position match the talent, temperament, and passions of the candidate.

Skills and experience come second to talent, temperament, and passion. All things being equal, meaning you’ve got multiple candidates who are a good fit for the job, it makes sense to choose the candidate with the best skills and experience. But these are secondary factors because they can be acquired. Skills can be taught and experience comes with time.

Talent, temperament, and passions, on the other hand, are different. They can’t be taught or acquired in the same way.

I define talent as natural inclinations, the activities that energize, the tasks a person can’t not do, the tasks they do unusually well with little thought or stress. For example, some people can’t go to sleep until a problem is solved. (That would be me.) Others go to sleep to avoid solving a problem! (My examples shall remain nameless!) Some people will straighten a room or organize a mess whether asked to or not. Others will never even see the mess. When job responsibilities align with talent, the work can be done quickly with relative ease.

Temperament relates to the suitability of the environment as much as the task. Some people thrive on deadlines and others crack. Some are blue sky thinkers while others are meticulous planners. Some love to build relationships and others prefer to work alone. Some demand answers while others are comfortable with ambiguity. When job responsibilities and environs align with temperament, the employee is energized and supported, not drained and battered.

Passions arise from both interests and values. When job responsibilities align with passions, motivation and determination run high.

Smart managers strive to find the sweet spot where all three of these overlap with job responsibilities. When a task meets the right mix of talent, temperament, and passion, obstacles surrender readily.
