>>54446692work, college, bars, you can meet all kinds of people pretty much anywhere.
hell, even online can work just fine.. one of my friends met his fiance on VRChat of all places.
people (especially internet incels, if we're being honest) seem to forget that there's nearly 4 billion women on this planet with all kinds of different combinations of personalities, preferences, and interests, and there's no 'one' place to find the kind of person you're going to be compatible with.
just clean yourself up, go out in public, and try to be warm and approachable to people. as long as you're working on controlling your nerves and not trying to overstep anyone's boundaries, you can start conversations with most passerby pretty organically.
it's just a matter of reading the room enough to know who is and isn't willing to be approached, and then trying to break the ice with whatever topic you think they'll find relatable. if they're receptive, great. see what happens from there. if not, then don't force it. just accept that you don't have that kind of common ground and move on with your life.
at the end of the day, starting a relationship is based on luck, and I'm not talking about genetics. being good looking might help, sure, but unless you're intentionally going for shallow people, it's not going to be the end-all-be-all of your romantic success.
