Curious if anyone has any non-standard tips for beginners. Not looking for the typical stuff like "practice more".

For example, a friend recomended I soak my fingertips in rubbing alcohol to speed up the formation of callouses.

Another example I figured out on my own as a way to memorize chords/notes... I always say the name of the chord/note in place of the "1" when I'm counting... A minor, 2, 3, 4, C major, 2, 3, 4, etc.

Any other good tips like these?
