A domino is a small rectangular wood or plastic block, marked with dots resembling those on dice. It is usually twice as long as it is wide, and its ends may have either a number of pips or none at all (i.e., blank). Most domino sets consist of a standard double-six set, which has 28 tiles. Other common sets include the double-nine and double-12, and extended ones feature ends with higher numbers of pips (i.e., more tiles).

A nifty domino video demonstrates how one small piece can generate enough energy to topple much larger ones. It’s a metaphor for how focusing on a few important tasks can have a large impact in moving other projects forward. This is an essential business skill.

Lily Hevesh started playing with dominoes as a kid, when her grandparents gave her a classic 28-piece set. By age 10, she had started posting videos on YouTube of her amazing domino setups.

Now she’s a full-time domino artist, with millions of fans. Her creative domino art reflects her love of the game, but it’s also a way to communicate some pretty big messages about life and work.

One of the main lessons she has learned is how to identify “good dominoes” — those activities that contribute to a larger goal and can have a positive ripple effect in your life and business. She describes them as challenging and often require a chunk of time and intense focus to complete. If you can’t do them all at once, she advises, just pick the one that will have the biggest impact and prioritize that activity until it is completed.

The lesson applies to personal and professional development, as well as business strategy. It is crucial to focus on the highest-impact activities that will give you the greatest return on your investment. Moreover, it is equally important to be able to recognize when a domino has already fallen, so that you can move on to the next project in the queue.

In the world of work, this means knowing when to quit a bad job and focusing on finding a new opportunity that will allow you to thrive. It’s also a good idea to be able to identify the dominoes that can help you rise up in your career, and seek out those mentors who are experts in their fields.

Domino’s CEO David Brandon understood this when he took over the company in 2011. The company’s core values include Championing Our Customers, and Brandon was adamant about listening to employees and making changes accordingly. He relaxed the dress code, put new leadership training programs in place, and spoke directly to workers to learn what they wanted from their jobs. These efforts helped Domino’s turn around its bottom line in a short amount of time. In addition, the company has been on the cutting edge of new ways to deliver pizzas, including through drones.
