Because we can sail a model boat for hours and not get bored. Changing the motor, waterproofing, making mechanisms gives us a thrill. If you want to know in detail you can read below.
Lately, I am dissatisfied with computers, tv, and media. I want to do two things in life WORK and STUDY, so I don't spend that much time on model boats.
Computers:
Anyone with any stupid idea can punch a few buttons and post it online for the world to see. The rest of us now have to do something with that. Also, sitting all by yourself in front of the computer screen is a lonely endeavor. It isolates you from your friends, your neihbors, and it contributes to the atomization of people. And it leads to a lot of Internet and Computer Addiction as well. A lot of kids now come from school, eat dinner and sit at the computer for the rest of the day.
TV and Media Glamour:
I said glamour because I did not know how to categorize this. It's too general of an idea but I am talking about TV, Magazines, Newspapers, and any visual media where photographs appear. Look at the photographs. Say it's a picture of a woman eating cereal in Vogue. Everything in the room has good decor and is in new condition. In reality it takes thousands of dollars to decorate your kitchen with granite counter top, stainless steel stove and it's impossible to keep the table from getting sratched, the stove from getting smudged with oil and handprints if you do any kind of cooking or eating. All media creates an expectation that we should surround ourselves with perfect things and keep them in perfectly clean, new condition. It's impossible to prevent normal wear and tear and there is no rational reason to, but people get seduced by this model. They buy the counter tops, they shine their stainless steel stoves until they look like new. It's ridiculous. It's hurting people.

Because I want to resist "The new spirit of the age - gain wealth forgetting all but self."?
...
Everything in the media is completely irrelevant to your life - a distraction from things you actually care about?
...
Media distracts you from leading a meaningful and constructive life?
...
Advertising tries to make you unsatisfied with your abdomen, your hair, your car, your watch, etc. in order to make you buy that new gym equipment, that new car, that fancy watch.
I can go and on like this, but I won't bore anyone who might (probably not) be reading this.
