3. The support
If your ex-boss was the right type of leader, then he must have supported you in what you were doing. You need to be motivated in order to move ahead and be more successful professionally. If your ex-boss appreciated your efforts and told you about that, then you are a very lucky person. In some instances bosses may be good psychologists who understand the human nature. Then they provide support outside your professional life too. Companies need to support their employees in every sphere if they want their business to bloom.
