In case of the latter, you will have to spend money on domain name and server hosting space that can cost you between Rs 3,000-Rs 5,000 a year. Self-hosted blogs have an added advantage that it allows you to customise elements and functionality of your website. In case of the former, you need to make peace with the tools and plug-ins made available by the service provider.
When I lived in Boston we had Allston Christmas...basically at the end of August when everyone's lease was ending people in Allston would just put their furniture out on the street for anyone to take. Never saw any MacBooks or electronics, but there was always some decent furniture out there for the taking. I was just a student as well so never really took anything but an end table, but if you had space, a roomy car, and a little restoration skill you could pretty easily pick up and flip furniture for some decent side cash (at least when September comes around)
Blogging is a great side hustle because you can do it at your own pace anywhere you want. It's not a quick and easy way to make money, but there are a lot of ways to make money side hustling while blogging. You can sell advertising, become an affiliate for other people's products, sell your own online product, and more. It does take time to build up an audience to be able to make a decent amount of money, but once you have a large following, you could earn over $15,000 per month or more (we do).
