Truth or lie? If you are VERY successful doing one thing you will be VERY successful doing other things too! Why?

depends on the person and what theyre doing and how good theyre at it

That can be true of some people but not of others. Many are capable of success only in one area. Others are universal geniuses, e.g. Leonardo da Vinci. I know such a man. He learns anything amazingly quickly. He was reading at age two and has the highest IQ in his high school's history. He has earned quick promotions and raises on many jobs. 

It sure would improve one's odds.
