If you are really interested in chess then there are certainly ways to improve. All of them take work, but you don't have to give over your whole life. A little every day is enough.
I can't recommend http://www.chesstactics.org enough. Tactics are crucial, both for offense and defense. Read this for understanding, not to skim, and do the exercises. Again, do the exercises.
While going through the above, or after you've finished, do tactics on chesstempo.com or another site. You will miss a lot of them in the beginning, but practice makes perfect. It's crucial to your game to be able to just see certain positions jump out at you, and timed exercises will help immensely.
For playing practice, find an online site and be willing to suffer through some losses as your ranking settles in. Maybe you have never won a game, but believe it or not you are not the worst player ever. As your rating is found, you can match up against others on your level. There are several big sites, and a ton of others. I use chess.com.
Another thing to try is "correspondence" chess, where you can play out a game over days, weeks or even months. Why? Because you can play many such games at once, you can play a bit when you have time, you can play people all over the world (no time zone issues), etc. But perhaps the biggest thing is that when you have 6 or 12 games going, you have to be able to look at a board and find the best move essentially from scratch. This ability to look at a board for what it actually is right now (instead of in the context of your plans from 5 moves ago), is a very good skill to have.
