     There's nothing wrong with tuming your hobby into a business. We're supposed to enjoy our work, right?

Just turn something we already enjoy into our career. Whether you're into painting or building furniture, you

know you feel proud of the result of your efforts.

     However, you should first explore the concept and do your market research and other planning. Don't

forget to consider what your day-to-day work life would look like.

     There is one very positive aspect of doing a business plan _____. You may be highly motivated to do some

planning and research, since this relates to an activity you know well and enjoy, and you therefore may be more

likely to do the necessary planning. This is a big plus! And once you see how to do this research, you may be

more likely to do it for other ideas you will come up with.

     Something I've learned over the years is that creating a business out of the first few ideas you come up with

isn't a good goal. If you are brainstorming ideas for your new career path, I suggest you list lots of ideas and

choose one or two that have the most potential to explore, as well as those that really draw you in.

     The evolution of your ideas is the best reason to explore those first ideas. The best careers come from

exploring the first ideas and finding out what will, and what won't, work for you. Make sure the business plan

you are creating based on your hobby should be one that you will enjoy and that will add to your quality of life.

Then start with your hobby, and enjoy the adventure of finding out where you will end up!
