Short vacation

It's my first time to write writing something here.
Before One week ago my vacation was started, but I had no idea first what should I what to do first. for a vacation.
I wanted to study my next classes, go on a trip in to the US, and just rest and practice English before starting a vacation.
However, it is just two week vacation! Otherwise, It has been over a week so far after starting a my vacation.
I just went to a ski resort near Lake Tahoe last week. That is all for me to I have done so far.

I thought the Total costs of the trip was about $500 for 4 days (actually 3 days).

but However, it was too expensive altogether costs for the lift ticket, and snowboard, clothing and car rental.

Even if I compare the costs mentioned above of a lift ticket, rent snowboard and clothing for snowboarding in the US with the costs of those in Korea, it is still too expensive for me.

If I was in Korea, these costs would have been under $50~$60.. Honestly, I'm not sure. :) , because it has been a long time since I've been to go to a ski resort in Korea.

Anyway, I wanted to write about something that happened for to me on in my notebook like the other guys here, but I don't have too short much time to visit here.
I have to read too much many articles and books for my next classes for in only a week.
I didn't expect such a bad life before coming to SF. (sorry to hear!)

I don't want to think first Korean sentences and say it in English, but it is still hard for me not to do.

(Don't really understand the highlighted sentence ^)

What have I written about so far? huh?

I think some native English speakers people could would be unable to understand what I wrote, but you can guess that !! :)
I'm looking forward to anyone's correction.
Happy weekend!

Kyoung Seok, your entry was fun to read! Hope life in SF gets better for you ~
