The man who controls his emotions controls his future. The man ruled by emotion is controlled by circumstance. This is not philosophy, it is mechanics. Every major mistake is preceded by emotional imbalance. Every major win is sustained by emotional stability. Master your internal state or remain reactive forever.
Learn the lesson: Once the words are out, you cannot take them back. Keep them under control. Be particularly careful with sarcasm: The momentary satisfaction you gain with your biting words will be outweighed by the price you pay.
Control your ego when you’re winning.
Control your thoughts when you’re losing.
Stay humble in victory and faithful in defeat.
God’s lessons are in both.
