The capstone is the last letter of the first name.

The capstone number represents the ability to complete projects the person started. It represents the attitude more than the ability, as the person generally has the ability. But the attitude can affect whether or not the person generally completes projects and, if yes, how the person carries out the actions required to do so.

Looking at the last letter of your first name, the letter "n," I see it is likely you prefer to have an audience when you complete projects, especially when completing difficult tasks.

The first letter of the name is the cornerstone, an indication of how the person approaches opportunities and obstacles – how a person approaches the starting of things.
