Teamwork is so important that it is virtually impossible for you to reach the heights of your capabilities or make the money that you want without becoming very good at it.

Brian Tracy is a Canadian-American business speaker and self-help author whose work, especially from the 1980s onward, focuses on sales, leadership, productivity, and personal achievement. This quotation reflects a recurring theme in his training materials: that individual ambition and earning potential are constrained by one’s ability to collaborate, coordinate, and lead within organizations. Tracy often frames “teamwork” in pragmatic, results-oriented terms—linking interpersonal effectiveness to measurable outcomes like career advancement and income—consistent with the corporate seminar and motivational-business genre in which he built his reputation.

The quote argues that talent and effort alone rarely translate into maximum achievement; the “heights of your capabilities” are reached through collective execution. Tracy ties teamwork not only to fulfillment or morale but to concrete rewards—status and money—implying that modern work is interdependent and that value is created through coordinated action. Implicitly, it treats teamwork as a learnable skill rather than a personality trait: becoming “very good at it” is presented as a prerequisite for scaling one’s impact. The statement also functions as a corrective to lone-genius narratives, emphasizing influence, communication, and alignment as multipliers of individual ability.
