Learning Photoshop CS5 - Day 1

Photoshop has always been a program that's intrigued me, but due to general lazieness and stupidity, I've never bothered to learn how to use it. 
But now that my school has given me a laptop full of Adobe programs I've decided to give it a shot. It's a pretty daunting undertaking for me but but hopefully I'll master it someday. I watched some tutorials on Youtube, a channel named Ch-Ch-CheckItsClan has some pretty useful tutorials. I also looked up how to change my language from Swedish to English since English is much more useful to me.

The picture above is my first succesful photoshop work, again it's pretty basic but I hope to be better soon. I could really use some helpful tips from people on how to be better and what I can actually do in Photoshop, since there's so much that's possible
Thx for reading Y'all
