I recently had a conversation with a friend who was struggling with managing a millennial. She asked me for thoughts on how to best manage her younger staff. As we talked, I realized that millennials take a bad rap for being needy for things that we as leaders and managers should be doing anyway.

I had an epiphany when my friend asked, “What have you seen or heard is the best way to motivate millennials?” Here’s what I told her.

One of your many challenges as a manager is determining who on your team has the capacity to be effective in their current role or an open position they want to take.

In Traction, capacity is the last measurable in the GWC equation and is defined this way: “Capacity means having the time as well as the mental, physical, and emotional capacity to do a job well.”

Have you ever picked apples at an apple orchard? Trees burgeoning with plump, perfectly shaped apples, ripe for the picking. Growing up in California, we had such a prolific tree in the backyard of our house. During August and early September, Mom would send me out to pick the apples and gather up the strays lying on the ground. I’d haul them into the house with a bushel basket and Mom would turn most of them into applesauce. The very best specimens were sliced up, covered with dough and baked into Mom’s excellent apple pie.

Most of the apples, hanging enticingly from the branches, looked perfect. Or at least until you grabbed one and studied it more carefully. You know, one side of the apple looked great, but when you turned it over you’d find a wormhole or a deep bruise. Damaged goods.

But how many times have you taken a bite before performing your due diligence—checking it out from every angle?

If you’re like most bosses, you do most of the talking. Frankly, this one-way-street behavior needs to change. Your job is to ensure that the dialogue is 80/20, where your direct report is doing 80% of the talking and you’re talking only 20% of the time. The only way to make that happen is to ask questions instead of making statements.

Here’s a guiding principle that will separate you from the pack of not-so-good bosses: A great boss creates a work environment where people are fully engaged and highly accountable.

How would you rate the level of accountability in your organization, on a scale of 1–10? If you’re like most bosses, you’d rate accountability low—maybe a 4. It’s one of the many people issues that frustrate you. You assign jobs to your people, only to be frustrated when they don’t follow through and accomplish them.

There are four truths that you must embrace if you truly desire to be a great boss. If you don’t embrace them, no amount of reading, teaching, coaching, or effort will make you great.
