After starting and growing a company to early success, entrepreneurs can sometimes let confidence go to their heads. Not only can over-confidence be a turn off for others, it can blind you to important changes you need to make at your company. Being confident shouldn’t make you think you can do no wrong. When markets shift, you can’t always stay the course and ride the success you’ve enjoyed so far. A confident entrepreneur will know when to make the changes that will set his or her company up for success.
