That's from Psalm 100.
To me that means: wake up every morning and cultivate gratitude. Consider the nature of gratitude: for what are you grateful? To whom?
Then, carry and proclaim that gratitude into your day. Be sure to acknowledge and thank the source of your blessings, whatever that source may be.
And as you draw nearer to that source of blessing -- in time, in spirit -- do so with a positive and giving frame of mind, and a joyous heart.
