Shaky hands before a presentation just mean you care. Present with the shaky hands.

The shaking is your body getting ready, not a warning that something is wrong. Adrenaline shows up when something matters, which means the symptom is evidence of investment rather than of incapacity. Waiting for it to stop before you begin is waiting for proof that you do not care. Everyone who has given a talk worth hearing did it with some version of this happening.

Plan for the hands instead of against them. Put the notes on the table rather than holding them, take one slow breath before the first sentence, and start with a line you know cold. The shake fades once you are a minute in.
