Pick up a meditation practice. Imagine you were told there's nothing left for you to do, but for your troubles, sitting quietly, focused on your breath, can bring you to states of ecstacy. Regularly filling your heart with love and presence.

Meditation comes in countless different forms, but all of them focus on being present with the experience you're partaking of. If the world is ending, you want to be present with the experience of it and have compassion for all those around you going through the same process. In the opposite scenario, where we're moving into a Utopian age, I still want to be present with the experience and have compassion in my dealing with others, so a meditation practice is foundational in all cases.

Cultivate a little stillness, a little perspective, a little good humor and joy. Understand the self and all the forces that drive you to act in certain ways, in order to alter your reactions to build habits more in line with your values.
