Metamorph

What do I live for? It's a question everyone asks themselves. We all want to give meaning to it, to have a reason to be here. The answer could vary, to name a few examples: wealth, happiness, love, power, knowledge, spirituality, freedom. There are infinite examples, but I wonder: There has to be one truth. One true meaning to this thing we call life. No one will ever know what it is, but how can I live, knowing that my very reason for existing might be false? Would I be able to live my life if I knew it was an illusion?
