Hello, I have been without a teacher for about a year now and my progress has stagnated since then, I am currently 'suffering' from the paradox of choice with regards to selecting repertoire- (The paradox of choice: an observation that having many options to choose from, rather than making people happy and ensuring they get what they want, can cause them stress and problematize decision-making.) On one hand, we should select repertoire that we love (encourages practice) but also we should be practical and methodically choose repertoire that will target our problem areas. I can currently think of at least 100 works of repertoire that I enjoy to listen to and would undoubtedly improve my playing, but I am having troubles with making the decision of selecting the "right" one. I have switched rep at least a dozen times now. How do you all make the right decision that you can confidently stick to?In addition, I have had some instructors encourage me to take on challenging pieces (Beethoven Op. 2 No. 3 or Grieg Piano Sonata) and others that recommend short-easy pieces (Schumann Kinderszenen) that will improve my sight-reading and ability to 'learn' repertoire (I have learned about ~ 10 pieces in my 5-year piano career), I would appreciate any advice!
