“Open means anyone can freely access, use, modify, and share for any purpose (subject, at most, to requirements that preserve provenance and openness).”not closed or barred at the time, as a doorway by a door, a window by a sash, or a gateway by a gate.

          In normal language we said as - 'something which is not closed and we can say that something which has no restrictions is called Open'. But the word Open has different meanings in different areas it depends upon the what we are talking about .  As like open the door , open a book , open mind, open thoughts , open shop, open bank, open schools , windows are open , etc. They are non living things .

           Keeping an open mind is always important. A important line I read somewhere that is - "be open to it being way better than you imagined".

         "I believe that having a open mind is one of the most important qualities we can posses, once our minds close, we stop evolving ".

I believe be open and honest it's most important.
