Most of us are guilty of some or all of those. Mostly when my sax player forgets to breathe it's because I'm thinking of something else instead of playing.
I never use a volume pedal. Better if I did I suppose but I only have two feet.
Only in recent years have I used a sustain pedal much. Never played piano, and they didn't have them for organ, so I never learned. Now I purposely make myself use it and I'm getting slighter better with it.
