I've had mixed success with dating apps. Sometimes they're great; sometimes they feel like a chore. But there are other ways to meet people!
Take classes - cooking, dancing, languages. Join clubs based on your interests. Volunteer. Ask friends to set you up. The opportunities are everywhere if you're open to them.
Be Approachable
Put down your phone in public. Make eye contact and smile. You never know who you might meet in your everyday life.
