At the end of this process I found myself repeatedly coming back to my hypothetical death bed. If I was laying somewhere right now facing down the reaper, what would I regret more? It then became crystal clear to me.
If I let MacSparky and the Field Guides linger and wither, I would never forgive myself.
I discovered the Mac Power users podcast a couple years ago. So much of what I use on my Mac now comes from that podcast and David Sparks specifically. Best of luck David.
