I normally rate myself on my play. Results are really secondary. If I made the correct plays during the day then I seen week in and week out positive expectation.

Easy math can show you what is possible.

Lets say you are playing 6 hours a day 4 tables at a low limit like 100nl? Your winrate is decent at 8bb/100 or 8$ every 100 hands.

The average table will get around 50-60 hands per hour, we will go with 50. We can see already that this will run around 16$ per hour, that is a pretty nice hourly wage for someone with his own hours and no education requirements.

We can also see that there is much room to grow considering highest limits online are 2000nl and 100/200 limit+
