I disagree. Lots of things are good when you're single and 25. Your money is all yours, you can be as self-centered as you want, no one gets mad (except you) if you have to work late, you're free to flirt with whoever you want. But all of that has been said. Fact of the matter is, if you think your life sucks, it will continue to suck, single or not. If you're got a positive outlook, more often than not you'll be happy, single or not.
