Lol. I've been my own person for almost 4 years. I am less concerned with finding myself than with finding God. Over a lifetime, I will change. But God doesn't. But yeah...I get that a lot. Apparently the guys think so too because you don't find a lot of people mature enough to get married before 25. So, don't worry! I probably will have plenty of time to "find myself" before I have a chance to marry.
I went to a Christian college for undergrad. I've seen people who immediately got a boyfriend/girlfriend, and get that ring by spring. I even know one girl who married at the end of her freshman year. She's divorced now. Being mature is different than finding oneself. A person can have a great head on his/her shoulders and still be unsure on the direction he/she wants to go.
