This doesn't mean you shouldn't.. or that you can't. You're a human being and you make your own choices of course, but generally my advice is DO NOT LTR when you're young. You shouldn't do this because, when you're young between like 18-30 you can improve your game, yourself, your career and everything. Let your 20's be your selfish years. Srs. LTR's can fuck you up, but if you do LTR when you're young it can set you up for some good lessons for the future, especially about breaking up. You go through the pain, it shapes and molds you. But a LTR can hold you back from some of your dreams if you become too attached to the girl, and put you in a crazy high level of oneitis. Use your 20's as a chance to LEARN about women. That way when you hit your 30's your already a boss and can choose the right WOMAN.
