If only going back in time and changing things would matter...    

*Edit: The smog is becoming a global problem, I lived in a place where you could not smell any kind of smoke 10 years ago... just maybe once a year when someone burned something down in the city.. but that was just temporary. And today that place has like a burning/stingy effect on your throat each morning when you wake up if you keep your window open during the night for some "fresh air", especially you don't stay hydrated during the sleep.

*Edit2: I dream of the day when I can enslave thousands of people and make them plant thousands of trees daily and dig artificial river trenches for miles each day! In the deserts! Paying them just 1 Satoshi per day or some sh!t like that..    (My goals in life seem a bit offensive and twisted, but I guess its for a good cause!)
