Magic isn't about showy powers or proving to others it exists to validate our beliefs.
Magic is many things, a lifestyle, a way to better yourself, a way to evolve the mind and soul into harmony with existance.
We dont need the world to recognise us as correct, because eventually the world will on its own.
If you feel that nobody believing in you, or that you need to provide proof and validate magic to those around you.. ask yourself "Am I doing this because I *Want* to be happy, or because I want others to see me differently?"
If you really think about it, and you're more interested in how others see you and your magic.. then prehaps you approached it with a mindset that will ultimatly be damaging to your efforts.
