You are what? 23? Relax. Start saving SOME money, but you are in your twenties once. Travel, have fun. Start thinking about what you want from your life so you can live with intent and not just let the world happen around you. Yes, you can set a solid footing by saving now, but do that by passing up on luxury, not by feeling shame and guilt.

Travel, hang with your friends, make new friends, get laid, watch the sunset then party until it comes up. You have the rest of your life to worry about the small stuff, you have the small window of freedom and enough money to enjoy it.
