For years, my prayer time was a worry session. No longer.
At some point, I realized I needed to praise God for answered petitions, not just machine-gun through the unanswered ones. As a boon, I discovered it bolstered my faith.
In addition to my long list of prayer requests, I have an ever-growing list of praise reports. Daily I write down at least one thing that was good, something God did. During prayer, I thank God for each and every one of them as part of my prayer time.
I have found that if I only ask for needs, I tend to get depressed. But if I also remind myself of His provision and bounty, it injects optimism like an energy-shot.
Adding praise reports has revolutionized my prayer time. I strongly recommend you do it to.
