What frightens you? Or what frightens someone else in your team? No doubt presenting is up there somewhere! Fear is good, it pumps the adrenaline that you require to reach peak performance. But there are 3 things that you need to do to conquer fear:
1) Recognise the fear and realise presenting isn't the issue - fear is the problem.
2) Decide to welcome the fear and just like any muscle in your body you need to train your mind to cope with the weight of expectation. Do this as any other exercise..build up gradually. Present to your mates, present to a small circle, then a team meeting, then slightly bigger. But don't rush this process, practice builds your confidence...build it gradually.
3) As you move through recognise your progress - give your mind a well done. Each time you speak is another step on the way to conquering the fear.....
