Given your extensive experience in construction and your current role as a surf instructor, your sunglasses business is uniquely positioned to cater to rugged, durable designs and stylish, water-friendly options. Your 19 years in construction likely exposed you to the need for protective, high-quality eyewear that can withstand harsh conditions, while your surf-instructing background highlights the importance of UV protection, polarized lenses, and lightweight, water-resistant frames.

Consider emphasizing these dual aspects for your startup in branding and product offerings. You could market durable, impact-resistant sunglasses for outdoor professionals and stylish, performance-driven designs for water sports enthusiasts. Your personal experience in both fields can serve as a compelling story to connect with customers, showcasing your deep understanding of their needs.
