In the real world it's 'save to invest but, in our world (in the business world) it is the other way round. Why is this so?
Because in the world of business we understand that a business is an investment scheme;one that has to grow, a plant that has to grow; a plant that has to be continually watered and put in the right conditions to grow. So you must invest in your business. Look for opportunities to do so. It does not matter if you go broke today, what matters is the result that it will bring forth tomorrow,You have to invest in knowiedge, resources, advertisement (publicity) etc
