Respect. It's a very important part of a successful doubles partnership. Each of us play differently - we have our unique qualities and flaws - but being able to play tennis and allow your partner to play their way is a recipe for winning.
You see - although it's a team sport and requires cooperation - it also requires space. Allowing the permission for people to play with their own flare - with confidence - is not only kind it's also how to get the best out of their game.
Give your partner the latitude to make their own mistakes and learn in their own time. You are NOT their coach and keeper!!!
