1 year anniversary for of my bartender career!

It is 21st Dec today, the exact same day in last year (in 2012 /or: one year ago) I started this new career (job) which I had never been doing before.

Nobody knew what would happen on my first shift, because I was totally new to the bar, anything to me was overwhelming(for example) ZERO ["I had zero knowledge" would be ok].
All bottles on the shelf looked at this new guy, I was so pressed stressed (out = less colloquial), I didn`t even know where to begin with my work. But later I found that I was kind of liked the feeling when I served a drink to a customer,. I started to learn everything about alcohols and wines alcoholic drinks/ spirits.

Till now, Today bar stuff is no longer not difficult to me any more, I learned the history of spirits and how every spirit is produced. There are two more important drinks also, The two most important, because most commonly consumed,) drinks are beer and wine.  I like both of them and I plan to go further with wine, because wine is getting more and more popular at every place in the whole all over the world. It is really a funny thing matter to learn about wine.

Do you like wine as well?
Coming from a country with great but underrated wines :) Yes, I do.
Was your English this good one year ago, or did it also improve along with your other enhancements?

However English's not my mother tongue, I just wanted to note what I thought could be expressed in a better way.
