What has worked for me: * Be aware of "signal-to-noise" ratio in your communication. If you want to say something - say it simply (as best you can) and then stop. Don't dilute your point with unnecessary prefacing or qualification like "but that's just my idea... oh I'm not really sure if I expressed it clearly". You will be very tempted to do this, but resist the temptation and let the silence sit a while, give people time to absorb your comment and to respond. * Have faith in the approach of "practice makes perfect", or if that doesn't work for you - an "iterative approach", whereby each time you try to articulate your thoughts (and probably fail initially - that's OK), the NEXT time you do so, you will be just that little bit better. You don't need to focus so much on making it perfect each time - that just reduces your practice frequency and will feed your anxiety through analysis paralysis.
