Is... boredom. - Tim Ferris
Just finished his book. Do you guys agree with this? I think that this might be true. I've noticed that when I reflect on my life, it is usually when I become too complacent and too unwilling to get out my comfort zone that I become for lack of a better word, unhappy.
I think this is why many times people don't want to retire, or if they do they try to find something else to do.
Time to get out of my comfort zone (feel free to make some cheesy jabs).
