If happiness always depends on something expected in the future, we are chasing a will-o'-the-wisp that ever eludes our grasp, until the future, and ourselves, vanish into the abyss of death.
But remember that the pain of parting from friends will be felt by everybody at times, whatever be their education or state. Know your own happiness. You want nothing but patience; or give it a more fascinating name: call it hope.
Material objects give rise to physical happiness, while spiritual development gives rise to mental happiness. Since we experience both physical and mental happiness, we need both material and spiritual development. This is why, for our own good and that of society we need to balance material progress with inner development.
