Remember the last time you awakened on a cloudy day. When you looked outside, your heart dropped. You had something outside planned.
Instead of going back to bed and sleeping the day away, you got up, took a shower and prepared for the day, just like you always do. Then, you looked outside again. Blue sky. Only a small patch, but it was there nonetheless.
Time passed, the clouds kept moving and, eventually, that little patch of blue sky became a beautiful, cloudless day. It can happen.
Clouds always move. The blue sky was always there. Remember the blue sky.
