Start analyzing your decisions from the perspective of a firm. In economics, a firm's goal is simply to maximize profit. Well-run firms spend money only if they can expect to make more money from their investment, and they allocate their resources to the most profitable use. You're not a firm, of course, and you have other considerations, but if you make the majority of your time and money decisions by choosing the options that promise the highest return on investment, you'll likely earn more money, and that's good news for your shareholders (you and your family).
Jack up your prices. If you're providing a skill, service or product that is in high demand and low supply, and you're making the most of your time, you should be making good money. Unfortunately, there are many people who are too humble or fearful to demand that they get paid accordingly. It's the pushovers in life who get taken advantage of and exploited, so if you think you might be one of them, learn how to stop being a people pleaser. If you work for someone else, ask for a pay raise or get a promotion, and if none of that pans out, revisit your career options as described previously. If you're self-employed, the first thing to do is to make sure your customers and clients pay up on time--this alone can substantially improve your income. Check your prices and rates against those of your competitors--are you undercutting them? Why? If you're providing a superior product or service, you should be getting at least the average, unless your profitability depends on mass production, in which case you're probably making a lot of money and wouldn't be reading this article anyway!
Buying and selling websites is becoming more and more common. As investors are looking for ways to diversify their portfolio, some are looking to invest in websites instead of pouring all of their money into the stock market. If you’ve got some capital saved up, you could buy existing sites in hopes of reselling them for a profit. This is more of an investor’s play, but it’s possible to make a nice living while only connecting to Wi-Fi.
