Be honest. You don't have to share the answer with anyone but yourself and you are doing yourself a huge disservice if you deceive yourself.
Do you work for your business or does you business work for you?
You can work in your business (employee), you can manage your business (manager) and you can work on your business (entrepreneur).
You can have a business plan, cash flow, working capital, investors, products and services, customers and an exit strategy. You can be providing a critical service to society.
But that does not answer the fundamental question. Why are you in business in the first place?
To answer this you need to know what YOU want. You need to know what your personal dreams, plans and goals are.
Money?
That is a cop out answer… everyone wants money. You can't take your money to the grave so, why do you want it? How much? What will you do with it? There are lots of reasons and infinite paths to earn money so why this?
The only reason to start a business is to have it accomplish something towards your life plan… to have your business work for you.
