Revisit your childhood to see what you loved doing. Make a list of all the things you remember enjoying as a child and test the waters to see if you still do. Then ask yourself how those past experiences can shape your career choice.
Make a list of people who are doing what you want to be doing. If you want to be a professional dance instructor, look for others and see if it’s something you could really enjoy.
Take a break from business thinking. While your current job and responsibilities take up the bulk of your energy, take a mental vacation and do something that’s out of your usual box and comfort zone. You might just find something you enjoy.
Do it anyway. Start doing what you love even without a business plan in mind. Get out and enjoy your passion with like-minded people and see where potential business opportunities and gaps in the market lie.
Then get to work turning it into a business.
