Listen to this interview with swim coach Bob Bowman, who I wrote about in my last post. Coach Bowman, among other things, is the coach of Michael Phelps.
In the interview, Bowman talks about what swimmers and their coaches should (and should not) do right before the race:
Note: There are some annoucements before the interview - but it's worth the wait.
By focuses on a technical detail - the process of success - rather than on the end result, the swimmer keeps his/her attention fully in the present moment - not on the larger meaning of the event.
Bowman's message can apply beautifully to speaking:
From the Green Room: Right before you get up to speak, try not to focus on the broader significance of what you are about to do (e.g. my career depends on this, I have worked so hard to get to this moment). Instead focus on something one technical reminder. (e.g. Breathe. Keep feet planted. Smile.)
