In Red Dead Online, wolves will spawn randomly while you’re out and about. A good habit to get into early on is to kill and skin them when they show up. You can sell the pelts at the Butchers for a pretty good price. Try to kill them with your knife or bow for better quality pelts. Make sure you head to the Butchers regularly to check what you can sell.
Yes, I went to bartending school after I graduated from college. When I didn’t get any job interviews, and my meager savings were drying up I needed a quick solution to make money for the rent. Five days later and $495 lighter, I graduated bartending school. I never poured a drink – I found a programming job the same week I was supposed to start bartending at a golf club.
This is an example of passive income that isn't quite as passive as it may seem. Yes, if you own one or more homes or apartments you can collect regular rent checks from your tenants. But in exchange for that, you need to keep the properties in good working order, along with insuring and paying taxes on them. You may need to chase down rent checks from some tenants, too, and you may have several months without rent checks when you're between tenants.
Know the difference between an asset and a liability. The dividing line is whether it puts money in your pocket, or takes it out. As much as you love your home, for instance, it is a liability rather than an asset because you put more money into it than you get out of it (unless you're flipping it or renting it out). Whatever money you save, invest it in assets such as stocks, mutual funds, patents, copyrighted works--anything that generates interest or royalties. Eventually, you might get to the point where your assets are doing the work for you, and all you have to do is sit there and make money!
