Granted. Your migraines are now completely cured. However, as per your request, anyone who annoys you now get said migraines. You parents, your siblings, your friends, and also your enemies. You can't say they don't annoy you from time to time, can you? Now they are all too out of it to do anything with/to you, including chores, games, and anything else you liked to do with them.

I wish to be able to control the essence of life itself, including the ability to create new life from nothing, and use this power for the good of the world, helping to grow crops from desolate wastelands to feed millions, cure previously incurable diseases, and save billions of lives.
