Classes, volunteer work, asking friends for help, the more effort you put out, the better your chances. I will have more dinner parties. This is a great way to meet people. You can take turns with a small group, each hosting a dinner party at yours or their place every week or so, with the rule that at least one or two outsiders are invited to the dinner every time 4. I will work on eliminating my own annoying habits.
Nobody is perfect.
I will refuse to put up with flaky behavior. If he doesn't call when he says he will, or she keeps canceling date after date, then move on. These resolutions are about creating a better love life, and if that means cleaning house, then so be it. If you have someone in your life right now, you could work out together. I will create more quality time with my partner.
