What should professional development of knowledge and skills of academic sport scientists look like? We address this question by first dwelling in what 'being a professional academic' entails. Professionals work methodically, typically specialising their knowledge and skills while strategically planning how to progress their careers, often not rocking the boat of the academic discipline they call home. To gain promotion, they expertly work within predetermined disciplinary boundaries, and are typically adjudged on objectified metrics that demonstrate a 'track record' in meeting professional standards, closely linked to university performance measures. Disciplinisation and performance evaluation becomes an issue, though, when rules, regulations and conventions prevent academics from exploring beyond their disciplinary walls, instead being lulled into "playing the game." The amateur, in contrast, typically studies for the love of it, enthusiastically embodying their interest as a way of life, maintaining the highest standards of knowing-in-becoming. This passionate exploration is not limited by disciplinary conventions or performance metrics, but by how far they wish to roam through boundaries of knowing. They are, in other words, a "wayfinder," making their way through life by corresponding with what holds their interest as they go. Never neglecting the "ethos of amateurism," we contend its potential value for professional development of academic sport scientists, embracing -- and perhaps even rekindling -- a love of continued learning with and from those we encounter.
