If you struggle with being discontent or unhappy; if your mouth always seems to be complaining; if you find yourself comparing yourself to others (why do they have that? why I am stuck with this? I wish...); if you all you can see is the gloominess, with no silver lining... THEN I have two books I highly recommend:
1) Lifelines for Tough Times (by Mike Fabarez)
2) Choosing Gratitude (by Nancy Leigh DeMoss)
A few of the women in my Bible study group had done the latter book and at the end of it they have a 30 day devotional and suggest to write down your thoughts, growth, etc in a journal. So I made journals, "count your blessings" journals.
