Love all the replies here.
For most, work has a way of governing your worldview. You wake up, dress up, rush to make coffee, fight the traffic, make it on time, sit behind the desk, keep user policy in mind while using the computer, put up with shenanigans, etc. Work has laid out the path for you. At the end of the day, you're exhausted.
Today, I wake up anytime, read what I want, step outside, breath the air, admire the beautiful blue sky and the morning sunlight and I'm still in my pjs. I go in the house, enjoy a cup of coffee, access what I want on the computer, kiss the beautiful wife as she walks out the door grumbling that she would like to be in my shoes soon. As soon as she's out the door, turn the music on, listen to Pharrell Williams and dance the morning away. Yeah, this is my world now. Anyone want to join me for a hike later this morning? And at end of the day, I'm exhilarated. "AGAIN, AGAIN!" as my grandson would say.
Now a days, it doesn't take much to make me happy because I realize my days are numbered. I can just look at my 3 yo jovial grandson and we laugh our heads off. I'm working hard on being like him.
When I worked, I worked at being satisfied for a job well done. Now, I just work at enjoying every moment in any circumstances. "Attitude determines your altitude", someone has said.
