How did YOU get good?

[Red_Diamond]

Here is a solution that has worked great for me in the past.
When looking at your past sessions, calc it this way:

#1 When you just break even, consider it a winning session.
#2 When you actualy won a few bucks, consider it a large win.
#3 When you have lost a bit, consider it as a break-even.
#4 If you take a huge loss, consider it as a small loss.
#5 When you really bust the bank, tally it as just Bad-Beats.
