Focus. Attack. There's just one opponent you need to beat. At its core, Formula 1 has a simple premise: defeat your team-mate. It doesn't matter if you're driving the title-winning Mercedes or a back-of-the-grid Sauber. You go into every grand prix with a clear objective.
Get the better of your team-mate in qualifying and the chances of scoring more points on Sunday increases. Achieve that consistently and everything begins to snowball - the focus of the team shifts in your direction.
New, improved aero reaches your car first. You get priority in pitstop strategies. Mechanics know they aren't being overworked in repair jobs and you become the golden boy of the team.
