Heaven and hell; the positive and negative aspects of or surroundings we see are due to how we look at the world through our own personal perspectives. Does everything, and everyone need correcting? Do we have to right every wrong? If all we can do is teach others; have we really learnt anything ourselves?
Every day is a sunny day; sometimes there are more clouds than at other times.
At the end of the day I may be right, I may be wrong, but I share this hoping I am one or the other.
