About a month ago, I turned—huge gulp—27-years-old. While I know I have so much more to learn about life, love and everything in between, I've realized that I've learned quite a lot about the world since I was a stubborn, selfish 18-year-old who thought she had learned everything she needed to know already. After years of bad dates, terrible "relationships," regrettable decisions, and lots of embarrassing moments, I have particularly learned a lot about dating. It took me a while to realize that dating in your 20s is so different from dating in high school or the early years of college. As you get older and become more mature, your priorities change and you start to really realize what you want in a person and in a relationship—and you also get to know yourself better.
