As Baal HaSulam and other great Kabbalists write, the most important thing is that every day be as new. The “day” means a moment, not daytime. That is why your every moment should be new! And this is the main thing.
Wake up, get up, and shake yourself at any time of the day and night as if you are reborn. Cross out all that was before: all our old problems and relationships. No past problems! No emotional baggage!
