"At this time in your life, you can't do what you're used to doing. You don't have time for all your heart desires to experience in your spiritual life. Nevertheless, do what you can do, even though it's precious little. Just don't deceive yourself by thinking that you can put off a devotional life until you have more time. Because when the years roll around and you finally do have more time, your spiritual habits will be so ingrained that you won't give more attention to your devotional life at all."
