A good disposition is a virtue in itself, and it is lasting; the burden of the years cannot depress it, and love that is founded on it endures to the end.
The secret is here in the present. If you pay attention to the present, you can improve upon it. And, if you improve on the present, what comes later will also be better." -- The Alchemist
Those who come a hundred or two hundred years after us will despise us for having lived our lives so stupidly and tastelessly. Perhaps they'll find a means to be happy.
Living in the moment means letting go of the past and not waiting for the future. It means living your life consciously, aware that each moment you breathe is a gift.
The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly. There are only two mistakes one can make along the road to truth; not going all the way, and not starting.
