Athletes practice with no crowds. Few people listen or are present when a musician practices. When do developers, designers and other knowledge workers practice? Do you type functions and language grammar repetitively? Do you design UIs and work on UX that you throw away?In this talk, both beginners and experienced developers, designers and product owners will learn about why deliberate practice can improve your performances -- err, pull requests. We'll talk about why and how athletes, comedians and musicians practice before they perform and why technology companies may need similar routines.We'll then put our new knowledge into practice with an overview of technologies that can help us practice without disrupting our daily performances. We'll cover tools like Gatsby, Apex/Up, and Now.sh to make ideas happen quickly. We'll discuss hackathons and other ways of incorporating practice into team settings. So that you find your own fun methods of practice and improvement.
