Get a better starting job salary with a PhD. If you don't have to have a PhD to get a job in your field of interest, having one, however, may get your a higher starting salary. Some job fields will employ people with both master's degrees and PhD's. However, those with a PhD will usually start out making more money than those with lesser degrees.
Start conversations with new people. Having a PhD is a great conversation starter. You can talk about your studies, what you researched or concluded and even the school you attended. Having the ability to talk about something new and interesting with others gives you an instant icebreaker.
Apply skills you learned from graduate school to other aspects of your life. Those who receive a PhD gain the ability to effectively research, to think critically and to question the world around them. These skills can come in handy in both your career and your home life.
Take your confidence with you. A PhD program produces confident graduates. If you tackled a complex problem or question and solved it during the course of your PhD studies, you may now have the confidence to tackle and solve other complex issues and problems that can arise in the future.
