Sometimes life sucks. Sometimes it doesn't.
No matter what life you've lived or will live, there are ups and downs all along the way. There is no way to say what life is better or worse, which one will end up making you happier. A 10-year-old in Africa may be happier than a 40-year-old in New York City, or an 80-year old in Australia.
I just collect the good memories and keep on going.
