One punch knock out

Eyes becoming heavy with blood and tears, arms and legs beginning to feel impossible to lift but instead of giving up you do the opposite, you keep going, you keep swinging because you would rather die then give up. All your training, the hard work, the blood, seat and tears it all comes down to this moment. Are you going to fight with everything you have or are you going to give up? The fight isn't between you and your opponent, it's between you and yourself, no one else.
