It's a big loss Not to know your way well , Not to know those people who are around you very well , Not to know yourself well , Not to know who is up and who is down well , Not to know how to spell words well , Not to know your size well ,and Not to know anything and everything very,very well ... Regretfully I can say all the above-mentioned indicates that That there is a big loss And you are in the closed circle of that big loss anytime .
