Any tiny seemingly insignificant idea can turn into a powerful demigod or a monstrous killer beast, a cute and cuddly elf or a scary pathological liar of an office mate. These things exist for a reason. For balance, I guess. Without them we would all just be waiting to die in our comfortable little box.
For creation to happen something usually is destroyed, annihilated. This could mean many things to each individual. Could be ending an old memory of an extremely painful past or recovering from being humiliated or rejected by someone that you admire or just maybe desiring a seductive plate of black forest chocolate cheesecake but cant afford to have. This will pave the way to creating new me...
