Trust your ability!
When you play a concerto with a small orchestra you don’t feel it is as important as Carnegie Hall. You try to work out all the little problems. Once that’s all done trust comes in.
I am playing the violin that’s all I know nothing else no education no nothing. You just practice every day.
For people who are really talented what you don’t say becomes extremely important. You have to judge what to say and what to leave alone so you can let the talent develop.
