Do you have to be "of the world" to be "in the world"?

No but it is a constant battle to stay above the chaos and keep your perspective.\n\nLove and blessings Don

There is no reason for the world.  It just is.\n\nPeople, however, being intelligent and creative, can create their own meaning and purpose.\n\nIMHO

Both. That's the nature of this world.

When you say "The world's coming to an end," it's a contraction - short for "world is."  You could also talk about "the world's problems," which is possessive - the problems that belong to the world.  You would only use worlds' (with the apostrophy after) when referring to something that belongs to multiple worlds, like "the two worlds' cultures collided."  You're talking about cultures that belong to more than one world.

In a just world, yes.  But you'd have a larger question if you considered our world just.\n\nGood question~~

Depends on what part of the world you are in.

write about what's in your heart...or your passion in life...or inspiration...something catchy...world issues are big right now...or something that no one knows anything about...like the lives lived in a different country...that doesn't get world attention but really should...

No, unless you come from another planet yourself.  Check out your word order.

Probably niether. Trivial in most respects, but a world in your own worth. We're either all everything or all nothing. Possibly both depending on the perspective. Just enjoy it wherever you are.

I don't understand why people expect "the world" to fix other people's problems.Most of the time,when people say "the world",they mean Europe or the U.S.,and then,if we do act,everybody starts getting all post-colonial on us,shooting up the blue helmets,or the peacekeepers,or whoever...and kidnapping NGO personnel,and all that other gangster crap.We don't intend to open a third,fourth or fifth front.\nMaybe the next time we go in to aid a situation,and get our people shot up,we should treat you to a real war,Ala Dresden,WWII.

You certainly can't omit "to have" and you shouldn't eliminate "to be" in (b). I don't quite agree that "I think it true" sounds grammatical anyway. If you like eliminating "to be", use "consider" instead of "think".

The present is the only time that exist. Have you ever been in the future? We are always in the "now" or "present" tense. Life is just different instances of "now". To live in the future is to live in a dreamworld. Sadly most people on planet earth lives in this dreamworld, some people even take it to the extreme by living for the after-life. Maybe "now" is all we have for eternity.

YOU be the change that  you want to see in the rest of the World.If you can improve yourself,that will be changing your world.We are not likely going to be around long enough to change the entire world,but we can change OUR world.

"To be or not to be" That IS the question!
