Instrument familiarity can really help people overcome different limitations. Every instrument only has so many notes it can play. There's a centuries-old Spanish guitar exercise for students where every note (within reach) is played one at a time up the neck on each string. Simple and not an actual musical exercise. It's expected to be performed starting with the earliest beginners before they even have much musical material under their belt to even practice or rehearse. If you are not already playing every note of your instrument every day, doing so will make you more familiar with all the notes. This can be especially helpful for the notes you have been missing. They've been missing you.
