If you started out your freshman year with your psych major, you may find that you have extra time to dedicate to your focus or even a second major. What's more, it makes good sense, too.
With a focus or minor you can start thinking about the rest of your career. A minor in gender studies could lead to a research project on women, solidifying your experiences and making the application process for grad school that much easier.
A double major is a great idea -- especially if it's a bit more...practical than psychology. The cruelties of the liberal arts world are many and you may find that having a second major in business or marketing will better serve your wallet in the future!
