Social Media is the Move
The hip thing nowadays is to literally spend every waking moment of free time on social media on your phone, so unless you'd like to be a social outcast I would recommend getting a Twitter account or a Snapchat account to keep up. You never know who might send you a message one day (This has some sarcasm behind it but it is sadly pretty true.)
Be A Dad
Statistically, all biological dads have attracted one mate minimum, which if you've attracted 0 is already infinitely better than you're currently doing. If you're not at 0 it's still pretty likely that being a dad will increase your chances for a multitude of reasons. Some of these reasons include but are not limited to: Great jokes, stunning fashion, having a dad bod (which are totally in right now and I am totally not biased with my dad-bod-to-be), and being excellent on the grill.
Humor Me
A lot of people say that you should be yourself when trying to be closer to someone you're interested in. This is bullshit, especially if you are a person that uses humor to try and relate to people. I don't have any experience with same gender attraction (and hardly any with opposite gender), but when it comes to talking to people of the opposite gender, their sense of humor is almost a foreign language. If someone you're interested is laughing at what you're saying or doing, odds are they don't think you're that funny, they just like you.
