Be Quantitative Instead Of Just Qualitative

In one of my jobs, my boss told me to be quantitative. For example, Qualitative is - 'It take too much time.', while quantitative is - 'It will take an hour'. We put a quantity or measure into sentence. This quantitative is very important. Always have an estimation of the things that you would just use words like large, much, low, high, etc. Instead use 7000 litres or 300 days or just 15 minutes, etc. This will give a clear idea to others when you communicate. 

There are many business ideas that come to mind. But seldom do we give it enough thought. If you are really looking at some idea, you should not just think about the idea in general, but also elaborate on the idea. True, you might not have idea about the response it might get or how it will be received by people. But you can always have some estimation to start with. For example, how much of capital will be needed if you start the project. How much time will it need, if it is a part time? What target customer base you are looking at? How many of them may actually buy? You can put pessimistic numbers to get idea about the general revenues you might have. You will also get an idea about whether the idea is feasible at all (looking at the possible revenues). You might also think about leaving the current occupation and starting with the new one.

The above was just an example. But if you try to be quantitative in things you do in general, then you will be very confident while presenting the ideas or while communicating. Instead of saying it will be costly, just give some figure to your customer.
