Henry still has an advantage because charisma is learnable.
Aspects of charisma can be learned however some aspects you are naturally born with and these aspects are your emotional intelligence. This mainly has to do with your ability to recognize and pickup on what others are feeling though subtle cues, the ability recognize your own emotional state and to control it, and lastly the ability to express yourself in a way that makes others like you. These things are not very easy to learn and for some they can be near impossible especially if they suffer from asperger's syndrome or simply didn't develop the foundation for these skills at a young enough age.
Not true at all, and you sound like a person who is just making excuses for themselves and why they're "doomed before they even begin". You certainly don't sound like a person who has done any reading on modern education psychology.
There is no such thing as naturally born talent, outside of the whole autistic savant thing, which comes with a pretty heavy trade-off. The idea that normal people are more naturally attuned to certain skills and subjects is a bullshit line popularized by western psychologists in the late 19th and early 20th century, based on nothing other than speculation. In cultures untainted by those Victorian era asshats, there is no concept of such division of skills, and average people perform relatively equally in all areas. You'll see a lot of teaching experts, stuck in their ways, STILL push the old lies that people have certain, specific ways in which they learn (visual, spatial, aural, etc) and that other forms cannot be adapted to, and that people who are strong in one area of subjects, say Art, are typically weak in other, opposed areas, say Science. There is no such thing as boundaries between skills! There is no such thing as "Emotional Intelligence" or "Mathematical Intelligence" any more than there is "Blowing a Snot Rocket Intelligence" or "Masturbating Intelligence". Classification of skills is just an arbitrary construct that people have created. It's all just learning, and learning is just another skill.
Now, given two people with equal base knowledge starting studies in a new area, you might find one of them picks up the basics more easily than the other. This is where the danger of this stupid idea of separation of skills comes in. In our Western society that believes in such wrong headed ideas, the kid who struggles with the initial steps of the task will likely assume he's just not suited to learning that subject and give up entirely, while the other kid assumes he does have a "natural talent" and continues practicing. If they would both just continue to practice, they would both get equally far. If this were a marathon, the kid with so-called "natural talent" is really only one step ahead at the beginning. At the beginning of the race, that might seem like a huge advantage, but by the end of the race there is no accounting for it. It's all about the effort you put in.
