How can a startup use the concept of positive obsession to grow?

Yes, there are several companies that have successfully implemented the practices of being obsessed with sales, customers, and teamwork. For instance, Amazon is known for its customer obsession. The company believes that leadership begins with customer obsession and works backwards to develop products and services. Similarly, Apple's obsession with product design and innovation has led to its success. In terms of teamwork, Google's emphasis on collaboration and open culture has been a key factor in its growth and innovation.

Potential obstacles companies might face when applying the concept of positive obsession could include resistance from employees who are uncomfortable with change, difficulty in maintaining a balance between obsession and burnout, and the risk of becoming too narrowly focused and missing out on other opportunities. To overcome these obstacles, companies could foster a culture of open communication to address resistance, ensure adequate rest and recovery periods to prevent burnout, and encourage a broad perspective to avoid becoming too narrowly focused.
