Commit yourself to never, ever playing mf, and that should reduce doing so to about only 75% of the time.

If you want to inhale silently, take in a given amount of air more easily, and more quickly, engage the nasal passage (the nose) when inhaling. Doing this then makes it possible to set your emouchure, with playing pressure, before you breathe, top and bottom center on mouthpiece rim, so that you, after your breath, are immediately ready to make that sound…..accurately and precisely…..and musically. Air comes in at “corners” of the mouth and through the nose. It is not only very easy, but it also is the correct way to prepare and breathe in order to play any brass instrument.
