We often forget to thank our ex-bosses for the positive things and changes they brought into our lives. 

1. Opportunities to learn something new

Once you start working for a new company, you realize that there are quite a few things you need to learn in order to become a better specialist. As a rule, bosses are understanding and give us some time to get used to the surroundings and the differences between your new and previous position. Admit that your ex-boss gave you that opportunity too and now you have become more professional.

2. Opportunities to grow and develop

Your ex-boss is one of the people who helped you to grow and develop. And this includes a few spheres of your life. You have become socially successful thanks to that person. Also, you have grown professionally and now can do your job much better. Your growth is not limited to that though. In your previous workplace you grew personally too. Be thankful for all of these opportunities. Appreciate your ex-boss for letting you become someone different and better.
