I feel like when I lose, I lose more money than I win when I win. I'm playing 5nl (pokerstars and bovada) and I'm not sure what I'm doing wrong anymore. I study 4hr daily and also play for 4hr or so daily.

For example: I just played a 1hr session (around 650 hands) that I really believe I played good poker, but I ended w/ -12.88bb/100. I understand the concept of variance and how this is really short term, but this is a common theme, so I though about posting this here to hear any insights.

Perhaps I'm not extracting as much value from my winning hands as possible?! Perhaps it's the rake?!

Thank you

EDIT:

I just recorded a 38' session on bovada. I had like 50 bucks there so I decided to play two 25nl tables only for the sake of recording for this video.

Now, I know that probably no one is going to watch this video from an unknown internet person. Seriously! I mean, poker is my main choice in life at the moment.

Unfortunately I don't have too much money to pay for this review, but if you or anyone else could take a look I will be FOREVER grateful. I don't have much money, especially since I'm from Brazil and our currency is seriously undervalued. But I'm willing to pay something as a sign of gratitude.

I believe this session can give an idea of how I play.
