Business is something which should be taken as long term investment and artwork of patience! It’s built stone by stone and you have to have considerable amount of hardship with it. I don’t think math should be put forth immediately. First you need to set up base for it, have recipe ready for your business which includes smart to hard work, management, plan executions and much more. Once you have product or service ready and available in the market then you should start with the ROI maths. Sometimes you could get more than enough sales and sometime you may not get anything. So it’s really upto that.
I agree that business is like we make long term investments, hard work and patience are important factors for success in business. I agree it's better
not to focus too much on calculating ROI when starting a business, it will only be a reason to stop if our ROI calculation is not achieved. The most
important thing in starting a business we must understand the products and services that we will offer, even better if we like the products that we will
offer. After that the most important thing is how we do promotions, so that promotions are maximized, determine the market that really needs
the products and services we offer. If we have done all that, we can start the calculation of ROI. We must remember that loss in business sometimes
we have to experience it first, so that we can evaluate our mistakes. Sometimes we need a long time for our business to grow, like any
long-term investment, we must be patient and never give up if we want to make our business successful.
