Rosh Hashanah is the beginning of the year. I've always liked it better than the Gregorian new year because Rosh Hashanah is actually at the beginning of my year. Sure, i've been at school for a bit, but it still feels like the dust hasn't settled so much on the year to come yet. But really any time can be a beginning if you decide to define it as one. The beginning of each day is a new start and one can make a conscious decision to live one's life anyway they please.
Beginnings, while exciting, also contain a lot of uncertainty, and there is very little I dislike more than uncertainty. But I am confident that this next year will bring happiness and sadness and love and trust and a myriad of other things that I cannot even imagine. And I'm looking forward to it.
