Because I sure don't. I don't know how it is further down south, where daytime duration is more consistent throughout the year, but here I always find myself anticipating it greatly, especially since we started doing the switch in early March instead of early April. It marks the period when the sun starts setting at a reasonable hour (up until yesterday there was no light whatsoever past 5:30 PM), and it also rises a bit later, so I don't get woken up too early as easily. I kid you not, if it weren't for DST, the sun would rise as early as 4 AM in June, and that's absolutely unacceptable. (Heck, 5 AM is already borderline NOPE.) On the other hand, if we had it all year round, it'd rise at 8:30 AM in December. Also unacceptable.
While I understand adjusting our biological clocks to it is a mild inconvenience, it's far less of a problem than having to wake up and go to work in the dark, or wake up way too early for no good reason and lack sleep as a result. Think about it.
