Sales reps are often failing in their roles because they believe their approach is superior to the established playbook of their company. Many come in with a strong sense of their own methods, dismissing the strategies that have already been proven effective within the organization. This mindset leads to a disconnect, where experienced sales executives refuse to adapt and follow the existing framework laid out by founders or leadership. The author highlights that while it's true that startups have their flaws, the most successful ones manage to find a way to thrive. New hires should integrate their skills into the current system rather than trying to overhaul it. The frustration often surfaces within the first few months as these reps struggle to align with the company's processes. The expectation isn’t to abandon personal experience but to enhance the existing strategies instead. The piece uses the example of major companies like Salesforce or Oracle to illustrate the absurdity of a new hire insisting on their own methods in a well-established environment. It emphasizes that while experience is valuable, it should complement the existing playbook rather than undermine it. Failing to recognize this can lead to quick exits from roles that might have otherwise been successful.
