A clear idea of the things you bring to a relationship, your value, and the reasons why someone would want to be dating you. The knowledge that fun, and change, and growth, do not suddenly end when you are in a relationship. And you can turn away the losers before you waste any real time with them. Enough financial stability that you are not going to enter a relationship specifically to help you out with your expenses or give you the luxury of doing what you want. Because you will need them at one point or another if you want to make it work in the long-term. The maturity to never again break up with someone in a shitty, disrespectful way, such as over a text message or by just dating someone else without telling them.
