Build Math Confidence  August 2019 Volume 123
Math Confidence Events 
Range by David Epstein
This book takes the 10,000 hours rule and turns it upside down as generalization builds success in many domains.  Rather than early specialization ala golfer Tiger Woods, Epstein promotes breadth ala Roger Federer who dabbled in many sports before choosing tennis.  
Chapter 4 (Learning, Fast and Slow) outlines the the benefits of mixed Math practice rather than just one type of problem as described in this study
Epstein encourages readers to broaden their horizons with "the most impactful inventors crossed domains rather than deepen their knowledge in a single area." and encourages range with "people who think broadly and embrace diverse experiences and perspectives will increasingly thrive".
