First you would determine what you would like your salary to be. You've dreamed about having a nice income to support your dreams I'm sure. Let's say right now you only make what your profit is giving you which might not be much. So let's say the first year, next year, you would love to have a consistent monthly salary of Ŭꯠ a month, every month. And every year you would like to be able to increase it so that after 10 years it would be at บꯠ per month. And let's say you would like to grow your business 10% each year.
I often see people split into two camps. On one hand those who almost ignore competitors in their business plan, because they do not want to think about the issue yet and feel so confident they have a great idea for the market regardless. But I recommend not being overconfident when it comes to competitors. They are still there for a reason, they are still around and in business for a reason, so view them with that in mind.
