One man’s trash is another man’s treasure. This is ever present in the sneaker world. I am an avid sneaker collector and a huge part of the culture is buying and selling your sneakers to keep updating your stock with your current favorites. I use a website called Kixify to buy and sell some of my sneakers and it is just like Ebay or Craigslist. Whenever I need money for whatever reason, I always look to see if I have a pair of shoes I am no longer in love with and willing to sell.
Monetize a hobby. While some hobbies actually cost money, others can be transformed into a profitable business venture. Ultimately, it depends on what your hobby is and how talented you are. You could turn your love of photography, for example, into a part-time gig taking family portraits and wedding photos or selling prints on Etsy or at arts fairs.
