This is the truth. Focus on yourself for now. Learn things, get good at stuff, advance your career, understand different perspectives, cook and eat healthy food that tastes good. Be somebody you really want to spend time with. A significant chunk of this is just you being confident and comfortable in who you are. Then people (including women) will be interested in spending time with you.

It helps to not be broke or ugly, but dressing well and washing yourself and smelling pleasant can get you pretty far.
