For over 50 years, based on the work of K. Anders Ericsson and many others, we have been developing the science of Expertise.  Popularized recently by Malcolm Gladwell, the concept of the 10,000-hour rule has begun an oft repeated statement meant to drive us all on to new levels of performance.  But despite 5 decades of research, and 15 years since Gladwell's Outliers was published, very few of us truly understand how to use deliberate practice to grow and develop new skills.  I've spent over 2 decades speaking, coaching and mentoring technologists in the advancement of their careers.  Careers in a field which moves faster, and changes more often, than any other on the planet.  What then is the difference between those who fail and leave the industry, those who keep up with the industry, and those who grow so fast that they shock those around them?  The use of deliberate practice is the start, but we must focus on the details.  Come learn how Conation, Cadence, Challenges, and Coaches are the secret ingredients which can turn repetition into growth.
