My method of Expression

Every artist has a tool for expressing his art. A painter has the brush, a guitarist has his guitar. Similarly all great executives have their tools for performance. Some perform by writing, some by speaking, some by presenting etc.

What is my method of expression? I am decent in writing (though verbose), decent in spoken English (again verbose) and also in presenting. How to achieve greatness in one of them. I have an answer: clarity of thought. All my problems stem from a lack of it.
