For the depressed.
If your soul is gray, search through your heart and mind for your passion. If you are so far into misery's arms, and have lost complete sight of your long-lost passion, think of everything. If one of those things awakens your sleepy soul, then that is your passion. Next, I want you to chase that passion. Tackle it, kick it, strangle it, stab it; take everything that you can from it. And in the midst of living out that passion, I promise that you will find contentment.
