As with any other type of education, listening to others is crucial when it comes to adjusting and fine-tuning the software development training we deliver.

The better listeners we become, the better software development training we deliver. Practicing our skills to listen to others is not difficult, and the benefits from doing so won’t be limited to our software development training skills.
