David's Tip of the Day: Practice Quotes by Gerald Klickstein - Take Breaks

“As a general rule, rest 10 minutes of each hour that you spend in the practice room. Rest more if you’re working vigorously or adopting new techniques. A sensible practice-to-rest ratio, widely recommended by teachers and medical authorities, is to practice no more than 25-30 minutes before pausing for a 5-minute respite. Many musicians opt for more frequent breathers and rest 2-3 minutes every 15 minutes or so.” Pg 12
