First, I would make sure that I got the Fast Track bonus, and I would pay more attention to keeping up to the green line. I would make sure that I got my 500 VP from bidding on Price Benders auctions each month. I would put in a standing order for 200 TCredits a month. I would be more careful in using up the VP available from the various one time actions.
Not really a lot of changes, just little things that would have saved me some money and aggravation along the way.
