Three Stoic principles can improve web accessibility work: manage yourself rather than trying to control external factors, treat every obstacle as an opportunity to educate and find creative solutions, and focus on what you can influence within your constraints. When faced with inaccessible design decisions, such as carousel patterns, accessibility practitioners should respond with patience and provide education on implementation complexity and better alternatives. The key is maintaining professionalism while persistently advocating for users, even when meeting resistance from teams who undervalue accessibility.
