Following on my last link, here is some advice on how to talk to yourself in those moments when you are tempted to give up or in:
Do you talk to yourself?
I don’t mean when you’re wrestling through your taxes or walking through your to-do list. But do you talk yourself, really? When you are fearful, do you command your soul to trust in the Lord? When your affections are low, do you command your heart to bless the Lord? As Paul Tripp is fond of saying, “no one is more influential in your life than you are because no one talks to you more than you do.”
