wolfmix, since you're new here (hopefully you've done a bunch of reading and know this already), let me just say it's essential on this site to swallow any pride when you ask for advice.
there are many GREAT players on this site and they will give you winning advice, usually couched in some in-your-face/u-suxor speak. disregard anything that comes off as offensive and listen to the reasoning and strategy behind what's said, and you WILL find success.
About your stats, obviously you've had some success which is great. But it's great that you're still exploring the ways to improve your game.
Aggressive poker is winning poker.
