Never discount anything of your past. God can pick it up and use it in the most incredible ways. If you have skills or talents you've put on the back burner, don't be surprised if one day you find yourself in a position where God gives you an opportunity to use them again. He draws from your life experiences at just the right time and in just the right place.
Your personal nourishment is crucial during times of storm. In panic moments, you'll cut a corner on your meals. You'll also fail to get sufficient sleep. It won't be long before you will set aside prayer altogether and you'll find yourself drained, spiritually. Increased emotional pain mixed with decreased spiritual renewal can be lethal to your faith.
