I buy Ruled Index Cards that are spiral bound, and I fill them with my favorite Scripture verses dealing with depending on God, praising Him, trusting Him, etc.
I keep these cards by my computer. I add to them, and I reread them.
When the computer is loading I read them. When I feel “stuck” in my writing, I read them. When my thoughts stray and my heart longs for what it cannot have, I read them. I am stregthened by God’s Word, and I am reminded where my help comes from!
