If you have trouble remembering that, then meditate. Meditation strengthens your center of consciousness so that you’re always aware enough to not allow your heart to close. You remain open by simply letting go and releasing the tendency to close. You just relax your heart when it starts to tighten. You don’t have to be outwardly glowing all the time; you’re just joyful inside. Instead of complaining, you’re just having fun with the different situations that unfold.
