Most people start their own business because they have an idea of what could work well and then they start to look at the actions needed to get the wheels in motion.
But what about if you want to be your own boss, or maybe working for someone is no longer viable due to health or family circumstances, so self employment becomes the better option.
How then can you find the right business idea? Firstly you need to identify:-

what are your passions?

what are your skills?

Start by doing some self analysis.

Take a large piece of plain paper and in the middle write your name.

Then draw branches out for each of your skills and passions.

From those skills and passions add further branches

Get creative!

In no time you will have a hole page full of possibilities of areas you could look into.
If you are not sure where to start, look into investing in

Franchises

Business opportunity packages

which are tried and tested ideas with all of the help and support to get you going AND keep you going in the early stages.
Perhaps you could 'piggy back' on a friend or colleague's existing business idea and enhance their skill set with your own for the benefit of you both.
I have teamed up with two online marketing specialists to help me to promote by business.
I pay them both a proportion of the commission.
They have the skills that I don't, so it makes perfect sense.
Being successful in business is all about being open to opportunities ALL OF THE TIME.
You have TWO ears and ONE mouth, so use them in that ratio.
So many people I meet don't listen.
They have so much to say for themselves that they miss opportunities by simply not listening.
So, keep your ears and eyes open for opportunities, + spend time doing some self analysis.
You will be surprised at what comes your way.
