1: Leave your comfort zone
As a pianist or musician, you probably have your favourite composers, a favourite era or a genre that you feel most at home in. That's very natural, though it is quite stimulating to try something different from time to time. Therefore, try to regularly play a piece that you would normally never start. And finding common ground is often easier than you think! Hardcore jazz pianist? From Bach to Prokofiev, there is a lot of harmonic inspiration to be found in classical music. Do you like Debussy? I see no reason why you cannot give Jef Neve's balanced compositions a chance. Moreover, different music sometimes requires a different mindset and a different learning process, which challenges you to break old habits.
