Your confidence can't be at the whims of every point, game or set lost. Knowing how to remain calm, not feeling discouraged or frustrated throughout a match can make all the difference. Nothing is more unnerving than playing someone who can not be discouraged, and refuses to lose no matter how far behind they get.

It's Mostly Mental   

Staying the course, and absolutely refusing to go down is part of what makes tennis so exciting: you watch people regain confidence in real-time.Sometimes you'll come out on top simply because you refused to throw in the towel.

Don't Quit When The Chips Are Down 

Becoming a great tennis player is similar to being an excellent professional, you're constantly analyzing your weaknesses and strengths, and adjusting your game. 
You can sabotage yourself by getting frustrated or being defeatist. Learning how to precisely manage yourself, and to stay calm and to dig deep in high pressure, high stakes situations can turn the tide of a match and a career.

You Must Be Hyperaware Of Yourself

When you play tennis, you're really competing with yourself. You're perpetually trying to improve: to hit shots faster, improve placement, surprise your opponent, make your footwork more efficient than it was the last point. If you try to blame others, like the coach, the opponent, the referee, etc., you're only hurting your game by not accepting your role in the outcome.

You're Responsible For The Outcome 

If you've won the first handful of points or games, well done, but the match isn't over until you win two or three sets. Momentum can change on a dime - your opponent is adjusting their game as much as you are to see what is effective.You must stay engaged in your performance regardless of how far ahead you are because you never know when circumstances will shift.

Never Rest On Your Laurels 

Great tennis players are unfazed by failure in the moment, they wait until the match is over to let emotions set in. Getting accustomed to failure and learning how to handle it well is what success is built upon.

You'll Fail Often  

With the Wimbledon Championships this weekend and the US Open approaching in August, tennis is in the heart of its slam season. Tennis fans wax poetic about tennis, often because it is the sport that most closely resembles life.
