Know what you can and cannot do. Some argue that successful marketing is more a function of luck than skill and they can't do anything about it. Other producers believe they can and should learn to anticipate most major market moves. Thus a key to successful marketing is to determine what you can do and what you cannot do. If you enjoy marketing, you will likely be reasonably successful at it.
People usually do well at the things they enjoy.
If you do not enjoy marketing, you likely will have very limited success regardless of your skills. Learn new skills. To be a successful marketer a person must be willing to learn new skills, whether it is understanding and using chart formations or understanding the use of option markets. A successful marketer must learn new skills and sharpen old ones. Develop an integrated and balanced management approach to your business.
