Hello guys, I kinda need your help...

Well, I'm playing poker for like 2 months, studying every single day, dedicating 10-12h/day for it, and I just can't get better!

I left the army in july/16 and since then I was looking for something to do with my life, and I found poker. I tought I was smart enough to do it, but know I'm not sure anymore. I'll show you guys my graphic below:

Those peaks of profit were before I started the study, and now I'm kinda stable. What am I doing wrong?

I'll be pretty much gratefull if you guys can help me.

Best Regards,
Haidyn.
