Private lessons beat a packed evening class if you're anxious. Classes move on a schedule; panic doesn't. Keep sessions short, 20–30 minutes, and do them 3x/week for a month before chasing distance. Progression is simple: steady ✨ exhale, front float, back float, roll-to-stand, then short glides and kicks.
Goggles only; ditch nose clips as soon as you can exhale without snorting. Expect weeks, not days.
