“There is nothing good or bad, but thinking makes it so”
We use this expression to tell if a particular situation could be a cause for Optimism (half full) or Pessimism (half empty)
We can also say the glass is there. I think the people that think that way are more detail orientated and follow Joseph Rudyard Kipling (An English journalist, short-story writer, poet, and novelist) philosophy ‘I keep six honest serving men (They taught me all I knew) their names are what, Why, When, How and Where and Who’
What is in the glass?
Why the glass is here?
When did the glass get here?
How did the glass get here?
Where the rest of the glass content is?
Who filled it up?
What should we do with it?
And many other questions can you think of?
