You are the one who has to pass the job interviews.
You have to ask for funding for your startup.
You have to recruit employees.
You have to make sales to customers.
You have to market and promote the good about your products and services.
You have to give your suppliers, manufacturers, employees and partners directions on how things should be done, or on what is to be done.
So if you improve, the business must follow suit.
So instead of seeking a better business opportunity, focus on the opportunity you already have by improving you. The better business is in your hands.
