Graduating, what High school? I assume you are living at home with parent/s

cities are expensive. Have you looked at what rent costs there? What would you be able to earn? Have you looked at what you would need to budget for living, rental costs, food, utilities, car,etc? Yup, add it up.

What do you want in life? You mention getting a job, doing what? what skills/education do you have, what do you want to do?

Focus on your life plans/goals, skip the women part of the equation for now

I live in a town with 20.000 people

20 whole people, Right down to 3 decimal places exact, that's a small town

But it will probably take another 1-2 years before I have saved up enough money to move out.

Have you considered maybe just getting a less expensive place in between both places. 20 mins is not far from a city for example.

Also, having multiple roommates can drastically cut costs in half. If multiple people split a mortgage that can still be relatively affordable.

You could also get better at framing where you live as quiet (or other words that don't make it sound like a desolate outpost of despair to these women)

Realistically man, if your town is irredeemable to a dating life, moving is probably a good option, look into finding ways to split costs with cool people you could see yourself living with and you could speed up moving out

It doesn't matter where you live as long as you have enough social status. I'm quite sure there are some hot girls in your town but they're all being grabbed by high-status local guys before you can even see it.

You should ask yourself what would increase your social status in your current situation. If you still don't have a car, this would make a big difference. Having a high-status job ( or any job, really ) would also change things further.

Anyone else here live in a small town and moved to a bigger city? How was it like?

Big cities are awesome. Many more opportunities to find what works for you.

During the weekends I always go there, and meet hot women. But as soon as they hear that I live in the middle of nowhere, I can see their excitement fade away.

Ok, you can make this work for you. Talk better about where you live, women are emotional creatures and will feed off your negative energy about where you live.

You can sell this better.... "I live in the wonderful little village of X, I'm regularly in this awesome city Y - I have business connections and friends here". Don't say you'll move there in future, this has to be all about now and today. Strongly imply that you're coming back though!

There are no great solutions, but I'd suggest working out how to make logistics to/from/at the big city work for you.

It's sort of like the brain drain except it's attractive women. After high school I noticed the same thing: all the hotties moved off to LA, Miami, NY, etc. Doesn't really matter how small your town is. I lived right next to Denver with a population of 2million and there was the same effect. Even in Asia there was the same effect and you could really see the difference between a small town like Klaeng and Bangkok.

Oh but it gets worse. Once you get to the big city full of hotties they are all chasing status. As you get into the upper eschelons they are all in harems called "VIP sections" of clubs. As you go higher you're getting into exclusive parties with pro athletes, musicians, actors, etc.

Is that really what you want to do with your life? Deciding where to live based on choices whores in harems make? I mean, you could just pay a whore for sex and then go back to your small town with your balls drained and happy you got to fuck a HB10 before she hit the wall.
