It is so easy to walk about life in a dreamworld, lost in the past or the future not really aware of even the fact that we are alive. Being aware opens up life, you notice that the birds are singing, the feel of a cool breeze on your face, a pigeon cooing.
The sound of a pigeon cooing has followed me all my life, well ok pigeons are practically everywhere, but the cooing has always made me feel at home. It reminds me of those long hot summer days in England when I was a kid, well I always remember them as hot they might not have been.
Being aware actually helps a great deal in life as you lose your keys less, remember where you put your phone etc, you just notice things more and it makes you feel more a part of your own life instead of external to it.
