I used to think the same way. Well, I still think it I guess, but different perspective on it nowadays. People always asked me how I didn't get bored just sitting in front of the computer all day, all they saw was "Sitting in front of computer" so of course it looked the same to them. But to me it's a world of difference between what you do on the computer so no, spending 12 hours in front of the computer was never boring, there are countless of different things you could be doing.

Then I caught myself thinking the same way about the fisherman that lives next door, who I pass every day and he sits and does something with his fishing nets. To me, it all looks the same way, so I asked myself how he can sit every day doing the same thing, over and over again. Asking him about it, apparently it's not so "the same" every day to him, as depending on the expected weather and what not, he prepares the net differently, and sometimes tries new things for various reasons. Maybe he is bored after all these years, I never asked, but I learned not to assume at least that things might look the same from the outside, but the person might be having a completely different perspective on it.

Like a taxi driver, it's just "driving all day" right? For a lot of people, seemingly this brings them a "no day is ever the same" experience and they love it and don't see any repetition, at least lots of drivers I've talked to felt this way.
