A study of violinists at the Universität der Künste in Berlin found that elite players spent the same amount of time practicing as average players, but focused their practice into two intense sessions per day, with more time for relaxation and sleep. This approach allowed them to be more efficient and effective in their practice, and to feel more relaxed and motivated. The study suggests that the key to success is not just hard work, but focused and deliberate practice. By prioritizing quality over quantity, individuals can achieve more and feel more fulfilled.
