Waking up in the morning feeling relaxed and well rested, fresh and ready to breath in life!
Going to sleep in the evening knowing you did everything you planed for the day.
Smell of the fresh air and morning cocoa :)
Can you name any else?
It's the things we don't notice out load but we're very happy when they happen.
It's the details, the uncluttered sensation of the world around us.
Give some thought about those, and try to make yourself more aware of them. Suddenly, life will become a much more enjoyable experience ;)
