I have a son who was considered gifted when he was young. I never thought curiosity and enthusiasm about things were gifts - just something that I wished more people should have.
I know it's his intent focus and a lot of hard work that turns a talent into something tangible. His true gift is focus and a desire to know every little detail about something that peaks his interest, and to turn that into what he wants. He's only 28 and is a top 10% wage earner. At a very young age he loved anything shiny, RPG game collecting, gemstones, cryptocurrency, higher education, investing, learning, always learning.
But in some ways he's as dumb as a stick (exaggerating but I say that with love and a smile) sometimes totally clueless of what goes on around him. I'm proud and happy he's able to attain what he wants. But so many areas of what is considered normal was lacking. I am extremely happy he found a girlfriend a few years ago and is more rounded now.
Prodigies - they are who I would actually call gifted. Whatever the field - science, music, art, etc - someone who just "knows" something, or can easily grasp concepts and actualize them, or has an extreme amount of talent in a particular field with little formal education.
