The small improvement nobody else notices can be enough reason to enjoy another evening of practice.

Progress in most skills is invisible from outside for a very long time. The chord that stops buzzing, the stitch that finally lies flat, the half-second shaved off something: nobody watching could detect any of it, and to you it is the whole evening’s meaning. Waiting for external recognition means waiting years for something you can already feel now. The private measure is the one that keeps practice going.

After your next session, note the one thing that got slightly better. Keeping a short record of those makes the improvement visible to you on the evenings when it does not feel like anything is happening.
