Focusing on what’s going on around you rather than what’s happening in your head is a powerful way to change your mindset, and one I highly recommend.
The whole looking outward topic came up at a Power Presentations workshop I was running; it was fascinating to see what a difference focusing inwards or outwards made to the participants.
When they were doing their own presentation – and focusing inwards – they were much more nervous than when, minutes later, they had to give an evaluation of someone else’s presentation because, clearly, they were focusing on something outside themselves. They looked and sounded 100% more relaxed and comfortable when they were evaluating and not just to my practised eye  –  everyone noticed the difference.
It was a valuable lesson in how your mindset has a profound effect on the way you act: my group went away promising to practise their presentations while focusing on their audience rather than on their own performance.
