They say that a penny saved is a penny earned. Actually, when you consider that you pay taxes on every penny you earn, you really do make more money by saving than by increasing your income, especially if the extra income will increase your tax rate dramatically. For example, let's say you have a choice between saving $100 or earning an extra $100. If you pay 15% taxes, then when you earn an $100, you only get $85. But when you save $100 off of your existing budget, you keep it all. To sweeten the deal further, if you take advantage of compound interest as found in most savings accounts, over time you'll start making money on the amount saved plus previous interest paid on that amount saved. It'll be pennies at first, but eventually the amount will multiply exponentially.
Send relevant writing samples. If someone asks for a marketing writing sample, send them marketing writing samples. Don’t send a finance article. Or a fitness one. It’s hard for a hiring manager to know how well you understand the niche’s industry if they can’t see a relevant writing sample. Apply to opportunities suited to your skill set and experience. Also, if your pitch doesn’t have a list of links to writing samples, it’s going to get ignored.
They don’t even have to be your bottles: Plenty of people are too busy or lazy to bother returning a six-pack worth of beer or soda cans for 30 cents and simply leave them out for curbside pickup. It may not be trash day in your neighborhood, but it surely is somewhere. Fill up a 50-gallon trash bag with cast-off cans, and you can redeem them for about $12 – it’s just a start, but you can do it again and again, and all it takes is time and hustle.
