edge
your personal edge is the domain in which you are most innately effective.
your edge is: the things you find easy but others find hard the things you find fun that others don't the things you find yourself doing to avoid other responsibilities/obligations
similar to your edge, you also have a handicap: the things that you find harder than others, that are especially unenjoyable for you.
refining your understanding of your edge and your handicap can help you figure out where you can have the most impact, create value, etc.
