If you get frustrated on the range or on the course you are facing a losing battle to shoot lower scores. Try your best to feel 'quiet' in your mind and not bother where the ball goes. The idea is to feel calm and composed, trying to find a deeper 'quiet' feeling and you will notice changes in your rhythm and tempo. You will have more time, your mind will have more space and you won't judge or analyse every shot. You will hopefully gain 'awareness'.
So many times I see people dashing onto the range hitting a quick bucket of balls and dashing off. They don't seem aware that they are rushing and getting very little feedback from their practice. They have no plan to their practice or pre shot routine. This is likely to form a habit of not thinking quietly about what they are trying to achieve. It is likely that this is also the way they play on the golf course!
