Observation, observation, observation.

Consider those around you who are successful at meeting people. Don't just think on where and how they met but observe their behaviour between one another. Everything from what they say, to how they say it including non-verbal communication.

Expectations - ponder on this too. What are your expectations? What qualities are you looking for? What is important? And of course, too, what is non-negotiable? Are these expectations realistic or may you have to change or tweek them?

Arm yourself then with what you consider both successful and desirable. Now get yourself involved in as much as you feel you can. Volunteer, join groups, seek out locations where such people who will meet your best match are likely to be.

There is a site called 'Meetup'. No it is not a dating site; at least not in a conventional way. It is a way of meeting GROUPS of people with similar interests. I will use a good friend as an example: she belongs to a walking group she met at this site, she also belongs to an event group whereby every month they meet to do something different (ski, gocart, bowl, laser tag, etc). I found a very good book club on Meetup.
