Is there a single word to describe someone who is good at everything? From a full variety of things... athletics, academics, even crafts & mechanics... one of those people who seems to have natural talent and drive for everything & almost seams to have the Midas touch?
I believe you are describing a polymath (synonymous with polyhistor):
A polymath (Greek: πολυμαθής, polymathēs, "having learned much")1 is a person whose expertise spans a significant number of different subject areas; such a person is known to draw on complex bodies of knowledge to solve specific problems.
