One piece of advice given to me by a friend years ago has served me well with regard to better fretting.* Keep your fingers as close to the fingerboard as you can while repositioning; this means they don't have to travel as far from one chord shape to the next and it can help to keep both fatigue and frustration in check. (My buddy gently made this suggestion when he noticed that my fingers had a marked tendency to rear back from the neck like an outraged tarantula whilst seeking the next chord. After lots of practice and assiduous application of his suggestion, my fingers still manage to make plenty of mistakes, but at least now they now scuttle swiftly across the fingerboard like a water-strider on a placid pond...)
