Here's a far easier way to receive passive income: Use cash-back or rewards credit cards. (If you're carrying a lot of debt or don't have the discipline to use credit cards responsibly, you're best off not using this income-generation method.) You can collect flat-rate cash-back percentages up to about 2% with lots of cards, while some cards offer more focused rewards or cash back based on certain kinds of spending or certain retailers.
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
