You can’t always have clarity of thought, so why worry if your mind seems a bit muddled right now? Any cloudiness you’re feeling could be the result of your own self-preservation techniques. Your mind needs a bit of a vacation, and it’s looking for a few moments during the day when it can switch off and veg out. Make it easier on yourself by finding that time before the afternoon. Even just turning off the computer or TV and letting your mind wander will help.
