Now what happens if I've been listening to professional quality music my entire life, but due to the fact that I lack any "real" talent, my music is just plain horrible? What if I just don't realize it, but my mind tells me it's fantastic......as one of the bipolarity's in me is realistic while the other side is in fantasy land?
Which one should I trust?
Everybody has this ability to create professional music in their heads. However, there are some people who merely lack the creative potential to unlock this skill. As a result, they only end up creating mediocre songs in their heads. If you truly think you have unlocked this potential and the songs you create in your head truly sound as though they are just as great as the songs created by famous musical artists, then you are justified to stand by that claim. If you know you are not deluding yourself and the songs truly sound that great, then that makes them great. You would know that you are not merely deluding yourself because by suspending all the qualities of delusion, you can arrive at the very core of a truth that is self-realized.
The same concept applies in terms of making the realization that a song you have created in your own mind is not that great. The whole idea that something is great just because you think it so obviously would not apply to those types of situations such as if you thought you were a great boxer just because you threw some flashy punches. However, it does apply in this situation of creating music in your head because we are talking something equivalent to LAD that emeraldsoul pointed out earlier.
