Mindset
My accountant looked at my numbers and asked: 'Is this a hobby or a business?' It was the most important question anyone ever asked me about Shot Pattern. Once I decided it was a business, everything — pricing, marketing, decisions — changed.

"Is this a hobby or a business?" — the question that forces the right mindset shift

For Duffett, treating the app as a hobby meant making decisions based on what felt comfortable (low prices, reluctance to promote, irregular work hours). Committing to it as a business meant charging what the market would bear, investing in growth, and taking the work seriously enough to quit teaching. The label shift preceded the revenue shift — the mindset change came first.
