What you feel sure is your greatest weakness may be one of your greater strengths. This much has been said over and again. For musicians, practice and the pursuit of perfection (i.e. chops) presents a unique type of navigational challenge - do you direct your practice time according to what you think you should be able to do or instead according to what you’re curious about?
In my musical practice, more time than I’d like to admit has gone to pursuing skills I thought I “should” acquire even when the practice failed to pack any real meaningful punch. The issue here is that the “should” practice idea can easily fall prey to concepts of sound or creative voice that distort the strengths of your weaknesses.
