Figure out what you are passionate about, and then as Nullo said, find a need in the market that will allow you to do it for a living. I have a few friends who have done that, and they almost feel guilty for getting paid (but then reality kicks in).
My dad worked for a large corporation for many years as a salesman, and they wanted to promote him and move him to another state in the US. He opted to quit and start his own business.
Dad was pretty visionary. He saw that Virginia was starting to create environmental protection laws, so he took his love for sales and became a manufacturers’ rep selling water, air and waste control equipment.
The challenge with having your own business is that it takes a wide variety of tasks in order to make it successful. Dad had no interest in the financial side of the business and talked Mom into managing that part, as well as the all of the administrative needs. Together, they became quite successful at running their own business.
Granted, it took several years before it started to pay off. The industry was new, his attempt to run a local cardboard recycling center didn’t pan out, and the commissions (his pay) often didn’t come in until a year after the sale.
The point is, he found a way to start a business doing something he loved, was good at, and was passionate about. And he picked the right people to help him run the business, starting with Mom, and then as the business grew.
You obviously have a talent for languages. The suggestion to start a translation service might just be the right ticket. I worked for a company that created online training, and now that the company has gone global, they need outsourced services for translating it into other languages. It would require sitting at a computer all day and rewriting text that you may not understand. Some people might enjoy that, and some people would quit after giving it a go.
The tour guide idea is also brilliant if you like people, love to collect information on the local area and its history, and have a bit of humor and charisma. I’ve traveled a bit and have been on many tours, and it is the personality of the shuttle driver, restaurant server, tour guide, etc. that makes all the difference in the experience. And it’s been reflected in their tip.
