Performance speaks for itself, every single time. Performance will say a lot more about you and your accomplishments over time than any marketing campaign ever could. Having said that, I see value in promotion, marketing and building awareness of your products and services and your own personal capabilities, but please don’t over do it and don’t make promises you can’t deliver on.
Share the spotlight and put others ahead of yourself and your own earned recognition will come in due time, it’s unavoidable.
