Gordon Cosby,  from a sermon in 1986, via inward/outward:

Give yourself to whatever is the special area of your own creativity. And if people do not understand, then simply know that it is their problem and not yours. Know that you must do it, else you will be angry.

Who knows what anger lurks within,  at an unknown level of depth for the surface?  I also have heard that anger begets depression.  Anger turned inward,  bottled up.  But that problem itself works to prevent us from the nurture of that special area of creativity.
