Designing VR for Better Focus in Repetitive Work

I spend a lot of time teaching surfing, where repetition builds skill, and I’m curious how VR could help with focus in tasks like penetration testing. When you’re doing something over and over, it’s easy to lose steam. In VR, what elements like immersive visuals or instant feedback could keep someone motivated and disciplined without feeling monotonous? I’d love to hear your thoughts on making these environments engaging and supportive for staying on track.
