The above chart shows the trend of my bankroll on Pacific Poker, as I worked my way through my own little training course.

As you can see, I started with a modest $20 deposit, and turned it into over $2,000. Notice the general upward trend, with occasional peaks and valleys. The three red-circled areas indicate times I went on a 80+ big bet downswing in my bankroll. The fluctuations look bigger as you move to the right on the chart, because the big bet size increases.

Notice that after moving up to the $2/4 level, I ran into some bad cards (or I might have had an inflated ego at that point and played recklessly, thinking I was invincible). When I fell below my 200 big bet threshold, I moved back down to the $1/2 limit again. It was painful to do, but it paid off in the long run.
