You'll find the right guy if you're not looking! A friend once told me, "How do you catch a butterfly?"
I answered him, "With a net?"
"No, you let it land on you," he said. I think that means a lot about the relationships. Wait for the right one to come by.
I'm 25 and still single so don't worry too much about it. Focus on yourself, your life. Finish school, find a job, be a fabulous independent woman!
