Joy and Sorrow

I quote from Khalil Gibran:

When you are joyous, look deep into your heart and you shall find it is only that which has given you sorrow that is giving you joy. When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight. 

When you have joy, there is sorrow, and vice versa. Something I need to remind myself as it is impossible to not have sorrow as it means that you have no joy. You need to have joy in your life.
