The author, who has been creating spreadsheets for fun, argues that everyone should start making spreadsheets for enjoyment, not just work. By doing so, individuals can reclaim control over their spreadsheets, unlock new skills, and discover new options within constraints. Making something for fun allows for a clearer vision of the end goal and enjoyment, even when things go sideways. It also reveals new possibilities and provides a sense of accomplishment. The author shares examples of how they applied new skills learned from making spreadsheets for fun to their work, including using Google Sheets' find/replace features to fix errors in a previous spreadsheet. By taking breaks to create something for fun, individuals can return to their work with newfound knowledge and confidence, adding value without anyone knowing where it came from.
