And when the crowds saw what Paul had done, they lifted up their voices, saying in Lycaonian, “The gods have come down to us in the likeness of men!”
Acts 14:11 ESV
The crowds can be all for you one minute, and the next crying about why don’t you do better. If you believe the fans when say how great you are, you should probably believe them when they tell you what a disappointment you are.
A better way is to keep an opinion about yourself in mind. You will always have things to improve and change, but you know what you are capable of today. Try to give 100% of what you have today when you are in the game. If you do that you can walk off the court with your head up whatever the current mood of the fans is.
