One of the top trends in 2019 is going to be boat building. Seems weird, right? But when you think about, building a boat is probably a whole lot easier than building a house, and people build their own houses all the time! Plus, as a hobby, it can pay off in a major way. Speaking of paying off, 2019 is the year that people are going to make an effort to turn their hobbies and interests into a way to make some extra money. Whether it's selling a good or a service, consider turning your side hustle into a way to add some money to your bank account.
