I had been at the church for > 10 years. I assumed the role of Music Director even though our first child was 1 month old, we were living 2 hours away, and were were planning on looking for a church close to home. I spent 4 years working on the design for a new media system.

how to manage a project and put in a new sound system. Everything I had done was totally wrong.
1.5 years later, we had canceled > half-dozen major outreach concerts, 2 major music festivals, we had a new projection system that didn't work at a cost of $8000, and I offered my resignation as music director.
