Entrepreneurial Mindset vs. Employee Mindset
As a professional athlete in a team sport, you are an employee. The IRS classifies you as an employee. Your team, coaches, agent and manager, all think of you as an employee.
And to them, you are.
But I recommend, strongly, that you think of yourself as the Business Owner, and an Entrepreneur. And you think of your life in sports as a Business, not a Job, not even a Career.
