For some people, the way to earn a living is to work for themselves. Starting a business is a completely viable option for many people, and a perfectly valid way to earn a living. Of course, some people go on to build large companies, but most businesses in the UK are very small and provide a good income for just a few people who are passionate about, and skilled in, what they do.
If you think that you can use your skills and knowledge to build a product or service that other people would be willing to pay for, then it’s possible that setting up a business is a realistic option for you.
To explore the options and get support to test and build your ideas into a viable business, speak to people who have done it already. There is lots of advice and support available.
