I’m a huge fan of blogging because I love writing and connecting with people all over the world. To give you an idea of what is possible with blogging, DollarSprout.com is part of a group of blogs that routinely brings in over $100,000 a month in revenue. While it takes time to build your blog up to that income level, you can get the initial set up done in under 30 minutes (no experience needed).
20. Etsy – If you like to create arts and crafts, you can sell them on Etsy.It’s completely free to open an Etsy store. You simply sign up, post pictures of your creations and starting selling. You can choose your payment option, but PayPal is generally the easiest. Etsy makes it easy to sell and keep track of your inventory. There is a small listing fee and they take 3.5% of every sale you make.

Go hunting or foraging for food. You may need to invest in gear and permits, but if you already have these, this is an inexpensive way to get your own food. If you're ethically against the killing of animals, it's pretty easy to forage for food, depending on where you live. Just make sure to forage only for food whose origin and properties you are sure of. Getting sick or poisoned is never any fun.
The last step resides in the concept of contribution. Even if you have no money, find a way to contribute to others. Look for opportunities where you can help those around you. Whether they're in need or not, this mindset will drive home the point that you have more than you need, even if you physically don't. Search for ways, every single day, where you can contribute either your time or your money to those who might be less fortunate, because that's the true essence of success in every form.
After an extremely intriguing conversation with Clothier, I began to better understand the concept of arbitrage and how anyone can use it to succeed in any industry. The difficulty here is first being able to identify opportunities for arbitrage, and later being able to fully leverage those on a larger scale. But once you find what works, expanding and scaling becomes almost instinctive and native rather than some grand hurdle.
