"The universe, this world and our own lives are the stage for a ceaseless struggle between hatred and compassion, the destructive and constructive aspects of life." Our challenge, moment by moment, is to continue striving to create maximum value and to never be defeated or give up, regardless of the obstacles we may encounter.
The struggles we face might range from the apparently mundane (summoning the energy to take out the trash or write a letter to an aging relative) to the vast (campaigning to ban nuclear weapons), but the essential challenge is the same. It is to overcome our own weakness, fear or inertia in a given moment and take action for the sake of the happiness of ourselves and others.
Ideally there is no separation between daily life and Buddhism. Exactly like what icy mentioned, to practice mindfulness. To have mindfulness is to know yourself, to know the condition or your mind and your life. This is to have understanding and discernment, to listen to Dharma at all times. After leaving the teacher’s discourse you still hear the Dharma, because the Dharma is everywhere.
So therefore, all of us be sure to practice every day. Whether lazy or diligent, practice just the same. Practice of the Dharma is not done by following your moods. If you practice following your moods then it's not Dharma. Don't discriminate between day and night, whether the mind is peaceful or not... just practice.
Our practice is like this. Try to have recollection at all times: standing, walking, sitting or reclining. When we perform our various duties smoothly and well, we feel peace of mind. When there is peace of mind in our work it's easy to have peaceful meditation, they go hand in hand. So make an effort. You should all make an effort to follow the practice. This is training.
