Talent is a small part, albeit an important part, of achievements. Achieving results is more about characteristics such as determination, self-reflection/critical thinking, finding balance in what you're doing, the right mentality, etc. Even courage is something important. (I'm sure there are other 'less fancied' characteristics out there that are too often forgotten, too).
Broadly speaking, talent is probably around 10-20% of the full picture (if that).
Unfortunately good old HBA was quite short on the less fancied stuff.
