Sometimes you just get burned out.
God and music, huh...
Chances are you might need an education some time in the future unless you only plan on ministering to my inbred stupid illiterate neighbors.
(They would not know the difference... but everyone else will know that you are an uneducated dolt!)
There is also that small chance that you will not make enough money as an uneducated Christian musician and will need some cash to live on...
Again... an education would be great to fall back on.
So try to figure out what the specidfic problem might be and work on it.
