A person wakes up in the morning, and makes himself a cup of coffee. He puts the bitter coffee in a mug, adds to it the sweet sugar, pours in the boiling water and adds some cold milk. A cup-full of contrasts, hot, cold, bitter, sweet. Then he says 'Ribono shel Olam, I don't know how my day will be; bitter, sweet, hot, cold, but one thing I know for sure, it will be שהכל נהיה בדברו - as You say it'll be.'
And that is how a Jew should start his / her morning, knowing that HaShem will pick just what's right for him out of the sea of contrasts.
