Lust is a passionate desire and love is a strong feeling of affection. Either may involve sex but it's possible to lust after material goods or love somebody without sex. The difference is that lust is a selfish desire ; love is unselfish, altruistic, and unconditional. You will soon recognise the difference both in your own feelings and those of somebody else. If you're searching for happiness, lust alone is not the answer. But you can be happy and love somebody with or without lust.
