I don’t believe the saying that you can’t teach an old dog new tricks. It is a lame excuse for anyone thinking about starting something new. Learning new skills is about curiosity and persistence.
Curious people are always seeking out new ways to improve and tend to tinker, poke and prod ideas. It’s got nothing to do with age. Persistence is remarkable because most new ideas don’t lead anywhere, and require a second look at more research and thinking or need to be improved over time. It doesn’t come quickly.
The dogs that don’t learn new tricks either give up too quickly or are quite happy lying in the sun waiting for dinner.
