Therefore do not be anxious about tomorrow, for tomorrow will be anxious for itself. Sufficient for the day is its own trouble.—Matthew 6:34 (ESV)

When you feel overwhelmed by a big project or goal, focus on today. What can you do right now that will help you succeed? Then, turn to God and ask for the patience and perseverance to keep moving forward just for today.

Lord, I have faith that I can finish what I start, and the process of working towards my goal is just as important as the result.
