Are you really having a bad day? The whole day? Perhaps a couple bad things happened among the hundreds of good things (or bad things that didn’t) for which you surely owe gratitude.
Every day is the first day of the rest of your life, but don’t wait for a new day. The same applies to each hour and minute. The day was never in charge anyways, you are.
Move forward. You’re creating the next 24 hour-day right now. Take back control. You got this.
