Live each day like it will be your last. I'm more than ten years ahead of you, age wise. I wake up thinking I'm 30 something until my feet touch the floor! LOL!
Getting your Music Minister to understand how Arrangers work (and don't work... unless you are as talented as Mason, Donny, UD, Gary and several others here) can be a challenge. Take time to show him how it will play songs pretty well with the left hand only via the one finger method. It might encourage him and others to give it a try if they don't play piano well. (Like me!)
Many never grasp how many "instruments" can be mimicked by the arranger... and now, entire choirs can be background singers. Arrangers are limitless... especially if you own a Genos.
