You must be familiar with the old adage that time is money. If you have spent few years in any industry, you will clearly understand that charging one for your time or work is just obvious. It is quite interesting to find that there are many people who have an underlying guilt about charging for their time from customers or clients or even general people. To be frank that is nothing to feel guilty about as this is the way in which any industry works. Consultants, who give their time in guiding others on various issues and jobs, are the most highly paid professionals in any industry. If they start feeling guilty about charging for their time, the profession will have no value at all.
