This is true outside of the entertainment industry too.
You want quick promotions? Be in a high growth area during a good time where the economy's not absolute shit.
Wanna get into a high-tier company with a good salary? Apply when they're desperate for someone with your skillset and the position you applied for.
Wanna find love? You can go on tinder or go out clubbing and find a different girl every night but the chances of finding someone you'll actually fall in love with are still basically 0% unless you're lucky.
