It is that we take ourselves too seriously. This sense of self importance in our opinions when they are as ar*es.
Including our negative judgementalness.
These will always be a hindrance to our ability to make music be creative, be a hindrance to be inspired.
To say we hate this and that music turn our nose up look down our nose at this and that music will always cloud us from inspiration will always be a hindrance for us being as creative as we could be.
We will still make music be creative yet not to the level we could and in only drips, trickles.
Creative bursts like a waterfall occur to us when we are somehow removed from these pukey aspects of our personality.
Also when we somehow become solely focused like a demon on the music, creativity we are making, not paying a millimeter of heed to anything else.
We can also work on our personality to remove these pukey aspects of our personality should we wish to be as creative as we could be.
