Some end-of-year thoughts. Few of them happy ones.
Rule of thumb, anybody who hesitates to spend $10 on a product that will improve an activity is performing that activity as an amateur (i.e. isn’t earning an income on that activity or doesn’t see it as an income-earner). This is a rule of thumb for the producer, not a judgement of the buyer. The idea is that if you produce a work that improves somebody’s professional activity your price, even discounted, should be much higher than that of an entertainment product.
