I am averaging right near $100/hr and I win near 60% of my sessions. I have had losing streaks where I was winning more often than that and huge winning streaks where I won less that 40% of my sessions. The point is, poker is all one long session. It is not what you won or lost this hour, this day or this week.
Quit worrying about win rates and worry more about making the right decision. There will be times that you make all the right plays and lose, but it doesn't mean you are a bad player. You cannot win every time. It therefore should not be your goal to "win" since the cards decide in the short run. Your only goal should be to play better than your opponents every time you sit at the table.

Good Luck.
