Hold a yard sale. If you have a yard or garage and plenty of items to sell, you can have a yard sale as early as tomorrow. By advertising your sale on local Facebook pages and Craigslist, you can also skip the paid newspaper ad and keep all of the profits for yourself. If you don’t have time to price everything, try asking patrons to “make an offer” or grouping similar items on tables with an advertised price (e.g. everything on this table is $5).
Start a bed and breakfast. If you live in a popular resort area or own a historic property, a B&B might be the perfect side hustle. Not only can you work at home with this career, but you’ll also score some tax write-offs in the process — although most innkeepers caution that the profession requires a lot of hard work and is more of an attractive lifestyle than a money-making pursuit.
If you want to become rich by your 30s, you should be looking at wealth-building opportunities that pay off quicker than traditional long-term investments. One of the best ways to do this is to get into the entrepreneurial game and own your own business. Once you own a business, you have unlimited potential to earn, although you also assume more risk.
