I follow this "invented by man" calendar because most people do and I need them, but not in my heart. I won't say my soul because I don't have one
For me it's just a matter of life schedule, productivity and business, without a calendar we couldn't make progress.
So, what do you think about this? Do you really believe we are in 2013 and tomorrow will be the end of the year and the beginning of a new one?
