Building a world of dreams isn't easy. It will take a lot of hardwork and a lot of miracles.
We have just begun in that department. We face all kinds of problems. Resource problem. New things problem, as in where to get new stuff everyday. Suffering problem. Pain problem. Death problem. Injury problem. Trauma problem. Violence problem. And a lot of undiscoverable and unlisted problems.
We should be able to build a world of dreams. Because we have pulled off a lot of impossible stuff till now. If we can do this, we can also do other things.
It's just matter of priority. If we prioritise this — building a world of dreams, sooner or later we will reach there.
And once we reach there, we will have no regrets. We will have everything that we ever needed or could need of. Then we can write a new story.
