If you're not interested in increasing the amount of revenue you're bringing in, you might want to check your pulse. Some of the most ingenious ways to make a buck are also wonderful ways to make you a richer (no pun intended) more well-rounded person. Luckily for you, we've listed some of them below.

Start a Business
Starting your own business is a wonderful way to bolster your income. Being your own boss can also do wonders for your mental state. Granted, there's risk involved, but there are also serious benefits. If you want to pad your pockets, you'll be glad to know your tax burden is decreased as a small-business owner. Plus, the IRS allows you to write off a greater number of expenses. Just follow the rules.

Learn to Earn
One of the most popular techniques for earning more is by furthering your training and education. Yes, it can cost you money now, but it will lead to higher wages and greater professional marketability. A 2003 U.S. Census Bureau study estimates that the median income for a high school graduate is $36,000 compared with $51,000 for someone with a bachelor's degree and $79,000 for a master's.

Learn a Second Language
Sure, we could get into a long discussion about how learning a foreign language will open all sorts of new doors for you, but the facts speak for themselves: Bilingual employees earn $5,000 to $7,000 more per year than their English-only counterparts. We think that will improve your well-being pretty quickly.

Don't Pay the "Plain Penalty"
Did you know that how you present yourself has a direct correlation to your earnings potential? Well, it's true. Nice threads can do more than make you feel like a million bucks. The Federal Reserve Bank of St. Louis found that well-dressed and neatly groomed people earned 5 percent more than their slouchy counterparts. You can't change your DNA, but you can maximize your appearance. Do it. You'll be (stylishly) laughing all the way to the bank.
