I was at an auction a few years ago where the entire stock of a local camera shop were put on the block.I recognized a someone in the crowd who I consider the best photographer in town.I saddled up to her and after a bit of a chat mentioned that I was attending the auction in the faint hope of purchasing a Leica.She asked me why and made a most profound remark "It won't make you a better photographer.Sure your images may be sharper but it will not improve your technique.Work on the fundamentals".
It still makes a lot of sense to me today.
