Lesson #1: The bad that didn't happen
Lesson #2: The good that almost happened
Lesson #3: Cautious optimism - don't tell anyone.
Take a deep breath. Here comes lesson number four. You can do this.
Smiling more is okay - even at other people. You can keep your arms crossed and sort of look off to the side, like the girl to the left - this is what we call a guarded smile. Don't let anyone tell you that guarded smiles don't count. They do.
The devil on your shoulder will be scowling by now...and plotting his revenge. If you have moments of weakness, due to that fuming evil fellow, feel free to slip back into cautious optimism for a day or two - until you feel strong enough to come back "out".
Only two more steps. Good luck!
