Answer:
Different personal and cultural traits can explain why even though we know that planning our activities help a lot, we rarely do it.
Japanese society is extremely structured and they plan everything. There incredible economic success is the result of that. Once I was travelling on the same tour bus as a group of Japanese tourists, and their tour guide requested them to give him their schedules since being on vacations meant not following a plan. The tourists got all anxious and nervous because they were going to do something different, which was scary for them.
That day I started to question myself as to why I rarely plan things, and on the next days I really tried to do it, but I failed. One of the reasons I failed was that I was the only one planning what to do, no one else at work was. I felt like Cameron Diaz when she was making plans about where she should be planning on how to have fun. It was really boring, that is the reason why Japanese don't have children or even girlfriends, its easier to plan what to do with a doll.
There is something nice and good about being spontaneous, although sometimes I still feel that I need to plan a little more.
