A side business is a secondary source of income that individuals pursue alongside their primary job. It allows people to explore their passions, utilize their skills, or generate extra money. Common examples include freelance work, online shops, or consulting services. Many people start side businesses to achieve financial goals, such as saving for a vacation or paying off debt. With the rise of the internet, platforms like Etsy and Upwork have made it easier for anyone to launch a side business and reach a wider audience. Balancing a side business with a full-time job can be challenging but rewarding.
