Nowadays, most people live their lives like a clock work. They wake up in the morning, go to work, eat lunch, work again, come home and then go to bed. And then repeat the same take next day. It’s a routine which is boring so when we have some free time we then try to break away from this routine.
We can do lot of things with our free time like go to the movie, play some sports or read some books. With lots of activities, some then people tend to make arrangement for their time. For example, a woman goes to London. She loves museum so she carefully planed out to visit all of the museums in one day. She has to get up early in the morning, spends two hours the most with each museums (there are lots of them in London), eat lunch, go to another museum and then back to hotel, exhaust. What does this seem like? A clock work, a routine and another working day. She may accomplice her goal of visiting all the museum with her carefully planed schedule. But what is the point of all the visit if you have to rush from place to place without enjoying at least one?
On the other hand, not making any plan, in my opinion, is a better plan. In the same situation if I have a chance to go to London, I would like to go to as many museums too. But I will not make any plan so I can spend may time freely without any restrain from the schedule. I just can walk around and breath in the atmosphere of the place, relax and enjoy the moment. No plan also means you can be spontaneous, go see thing that catch your eyes at that moment. Ant that will make your time more interesting.
