I too have some feeling of inadequacy after reading this thread.
But then again, I am an avid woodworker (35 years) and photographer (38 years), and have accumulated top end professional equipment for each. I've been previously diagnosed and come to terms with NAS (Nikon Acquisition Syndrome) and LAS (Leica Acquisition Syndrome). I am even selling off one of my five camera systems that I don't use much anymore to fund dive trips, so I feel in my heart I am making strides in my recovery. I've only been diving a couple of years, so I guess my inadequacy might be forgiven at this point.
I have done better in the UW photography world, and have managed in a brief time to have assembled a complete DSLR FX and Micro 4/3rds systems.
I am trying hard, though, to cure my shortcomings....just give me a little more time....a few more orders....I know I can do it.....
