Congratulations, Aaron. That shows what's so fun about this game. We all have a long term goal in mind of where we want to be or how good we want to become, and even though that changes as time goes on, the intermediate goals remain the same as we progress and until we meet them.
For example, Aaron, now you're probably going to aim for a -5 because you know that it's there; you just need three less mistakes than the last time. Or if you're like me and babysteps is fine, then a -3, then a -4. Either way, good work and congratulations.
