the perspective of perception
I don't know, — means, — I don't bother to find out. I'm not able to, — means, — I'm too lazy to look for a solution. I don't understand, — means, — It's hard to think all by myself. I'm a negative kind, — means, — I don't care enough. (but) When "would want" becomes, — want! When the "should" becomes, — have to! When "first and then" becomes, — now! Then — and only then, — your wish will operate in full to come true.
