'Enjoyment, that's the secret' - Emmanuel Pahud
When I was younger I used to get nervous about playing in front of people. I was 'shy' and still am in certain situations. I put myself under stress! As I became older I realised how much of a privilege it is to play an instrument and a joy to play in front of 1 or 2 people or a few thousand. I made a conscious decision that I was going to enjoy every second of playing. Each moment in life cannot be relived. Time marches on and the present is only that. Quickly it becomes the past, so why worry. Do the preparation and do your best. Emmanuel Pahud talks about this so well.
