Openings

Develop your pieces, dont give away material, get your king safe. Look out for your opponent's mistakes. e.g If you play 1.e4 e5, 2.Nf3 and your opponent doesn't defend his pawn, chances are it's a mistake and you wanna take the pawn.
OK I think a more detailed answer might be needed:
what sort of game do you like?
Do you like open games with lots of tactics or closed games with more positional chances?
It appears from looking at your games that you like 1.e4 as white.
May I make the comment that you should try not to move your pieces more than once in the opening unless it is necessary.
I wont comment on current games but...
Your game against Pskogli you played your Bishop to d3 without the d pawn being moved. Generally you dont want your bishop to be on d3 with your pawn on d2 because it is then hard to develop your other bishop.
I'll leave it at that at the moment.

Thanks, I will consider all your advice especially yours trentthechessnut.

I kinda new to the whole opening thing, so could anyone give me some advice as to some good ones, or at least some books. I couldn't find many at the library.
If you are starting to study the openings in chess, the least intimidating book is probably "Basic Chess Openings" (with king pawn) and "More Basic Chess Openings" (with queen pawn) by Gabor Kallai. The author lucidly discusses the underlying principles behind each opening without confusing you. Also you can get it really cheap secondhand from online book stores.
