Regardless of what the critics say, self-promotion is a very positive act. It can turn things around in an instant, making people believe in the capacity of their passion and how they can create changes in all aspects of life. Here are the reasons why some people, most especially the successful ones, aren't ashamed of self-promotion, according to the Business Insider.

1. All of the successful people are in sales

Susie Moore of the Business Insider says that every single one of successful people is in sales. Moore believes that if you are working with human beings involved, then you definitely are in sales.

2. It has apparently become normal

Sharing huge career announcement on social media isn't something that people should be shocked of seeing, Moore says. It encourages the possibility of others looking at it as a positive motivation to be able to do as good, or twice the better, as the person who just let the world know of their achievements.

3. Not everyone is actually paying attention to your great work

"Busy, hectic working environments are common. I have worked in organizations where my successes have not been recognized unless I have expressed them to my manager. Communicating my success has been welcomed as great news by my managers, who otherwise would not have known how well work was progressing," Moore wrote.

4. If you are an entrepreneur, it's kind of unavoidable

How do you expect people to find you? By promoting yourself, of course. Showcasing your work and sharing to the world how you have actually done great things can be your ticket to the train to success.

5. By self-promoting, you could as well be helping others

Acknowledging and taking ownership of your talents, according to Moore, is the very first step you take if you want to achieve professional and personal greatness.
