The document provides tips for optimal learning in challenging times from Professor Billy O'Connor of the University of Limerick School of Medicine. It discusses how neuroplasticity allows the brain to change in response to experience. Effective learning involves analytical and holistic approaches, taking risks to drive new learning, and focusing attention. Tips for fast learning include deconstructing skills, learning enough to self-correct, removing practice barriers, and committing to at least 20 hours of practice. MENDing with a growth mindset of exercise, nutrition, and determination also supports learning.
