I think it depends on how you started your day. If you start your day right with all positive thoughts in your mind and can face any challenges that life might bring, you can make you day a good day. I know every day in our life we face different challenges that made our mood bad but we can face it by doing positive things and making things right. Just always give our heart to God and I know those things that made our day bad will go away. Pray and believe on God. ^^
