Chris,
The talent for making models comes from many places.
The attributes you spoke of are a must, but artistic creativity, a mild case of obsessive cumpulsive disorder (how many Shermans have you built, Robert?), tenacity, willingness to learn new skills, hand eye co-ordination, ability to learn from mistakes and practice - all of these are vastly important.
But the ONE THING that sets us apart is simple. We just are.
It's like my wife trying to tell me that she never wants me to ride a motorcycle again. The thrill and desire to ride will never go away. Ever. It's a part of me. Nothing can change that......................It's the same with building models.
The only time I'll stop building models is when I'm blind or dead - all other obstacles can be overcome, with tenacity.
Cheers
