Learn how to manage your money so that you control your lifestyle, rather than letting it control you. Start simple by keeping track of your expenses, then develop a budget so that you aren't spending all of your money every month. Eventually you'll get to the point where you have the option to do what you enjoy in life rather than feeling like you're trapped on an endless treadmill.

If you want something to do right this minute, just start working with Mint or You Need a Budget (depending on how automated you want things).
