You're on the right track. Keep doing what you're doing. The most important thing is not what you make now, but what you can make in the future. For a 24 year old making $40k, you're doing pretty good. What is important right now is not how much you're making, but how much you're saving. That's what will matter later on. Make sure that you're contributing as much as you can to your 401k, especially if your company matches. You should put in as much as they will match because that's a 100% return, which is better than anything you'll find in any other kind of investment.
Money magazine had an article in their January issue about where you stack up. You can enter your age and your income and they'll show you what the average net worth is by both age, and income. For your age, median net worth is about $400, so if you've got more than that in savings and 401k, you're ahead of the game. For your income level (I assumed $42k), median net worth is $20k, but most of those people are probably older and have been saving longer. You can also take a look at what you need to do to hit certain goals, like pay for your kids college or become a millionaire. You can see more at the link below.
Keep working hard, set goals, and then do what you need to do to get there. I think you're on the right track just by virtue of the fact that you asked this question. Well done.
