I suffer from disappointment in others and in myself.
One of the disappointments in my life concerns other people. The other day I was going through Michael Hyatt's Best-Selling book, Platform: Getting Noticed In A Noisy World. He used a phrase I had not heard in years about folks who appear to be more than they are. It's said to have originated in Texas, "He's all hat and no cattle."
The meaning of "All hat and no cattle" carries the idea of a person pretending to be something other than their true self. Too often I caught myself believing the PR about such folk, especially within the ranks of my calling. I spent a little time thinking perhaps we should outlaw the hat. A more sensible approach is to take a good look beneath the hat.
I learned from disappointment in myself to put a lot of time into personal development or more biblically correct, growth. David of giant slaying fame, a man after God's own heart was more normal than you may think. Here is a key to his greatness: 2 Samuel 5:10 "And David went on, and grew great, and the LORD God of hosts was with him." Peter said it this way, 1 Peter 2:2 "As newborn babes, desire the sincere milk of the word, that ye may grow thereby:"
At some point David's father said, "Son, if you're going to wear that hat, at least get some cattle."
