THOUGHT:
The best preparation for tomorrow is to do today's work superbly well. A job worth doing is worth doing well.
Challenge
You can only do what you can do. Don't spend time worrying about what you should do tomorrow. Spend that time thanking God for His blessings in your life today.
Verse
Do not worry about tomorrow; tomorrow will take care of itself. Sufficient for a day is its own evil.
