How...

So how does this work?
Throw it together and see good results.
Spend hours and tears and I don't see the Spirit.

Tell me, teach me how to do this.
How do I know when, and how?
This isn't my job, but it's a call.

Get wisdom and insight.
They won't let you down.
Try is all I can do.
There's no rhyme and no reason as far as I can tell.
So how...?
