WARNING - Do not get
before getting this achievement. There is a glitch that has been there since launch that once you get the Superstar trait, you can no longer progress on your traits, essentially locking this down. I hit this, then found out on the EA support forum that this was an issue and had to start a new player.
You will want to grind out traits in The Streets for this. Depending on your type of player, some will be easier then others. For gold in most, you must get to level 60, but there are a few for each type of player that do not require that. Like wind sprints, but this requires you to get to level 30 and win 55 streets games, which will put you close to 60 anyways.
