Here’s a corrected version of your text:
"You don't know what you're doing, but it only takes 10 to 20 minutes to ruin your entire 80 to 90-year lifespan. How can you be wise and enhance your life instead of being a fool and shortening it? God created you, and you have been given the power to create and destroy. Do not expect God to perform miracles; your destiny is determined by your hard work."
