Well, first of all we definitely need to use standardized time just so we can all operate as a society and have meaningful conversations about things taking place in time that involve more than one person. While I do appreciate your notion of personal duration that is different for everyone, I believe there is a good reason for sticking to the mechanical ticking of the clock. That would be a funny world. No one would be able to hold a meeting unless through a pure coincidence! :)
But what about time I don't like? Well, for one thing it keeps on passing. I hate feeling rushed and this mechanical ticking away makes me feel inadequate. It seams that no matter how hard I try, I am unable to do/finish/begin anything in the correct moment. In other words, my body an mind don't feel in sync with the time represented on the clock. Instead the rhythm, which supposed to be common to all of us, feels almost arbitrary. I do like to sleep in and stay up at night, I'm almost always late everywhere, and my experience of time is never uniform. An hour can stretch or shrink and its duration seems to depend solely on my perception and psychological state. I can imagine that most people have a similar experience of this phenomenon. If that's true, then why do we pretend that time is uniform and the same for everyone? In that sense, I think I just hate our present understanding of what time is and how it's supposed to be used.
Ha ha ha! I didn't mean to seam snappy... I thought that I'll have a different take on the lists everybody has been making :) Instead of enumerating all those wonderful things I like, I made it simpler and listed what I don't like.
