The way you look at things would determine whether you can achieve success or not. However success can be yours if you have an open mind along with some self confidence. What appears complicated can be handled if you are patient and have confidence in your self. Otherwise you would fail. Many things can be done to improve on this area so that you get the best of the gaming experience.

Approach the sport with an open mind and embrace it. If you just half attempt the sport then you will increase the chances of getting hurt, decrease your chances of success and wish you had never picked up a tennis racquet. It does not matter for how long you have played the game. A player who approaches the game with a positive attitude is like to play a better game than some one who is in a bad mood.
Simply start to take mistakes as leaning opportunities. If you find you mostly make mistakes in the timing, when you have to swing your racquet, then concentrate on how you can improve on this area. For an overall improvement in your outlook, you need to treat every mistake as an opportunity to correct and learn more. Hopefully that this would cheer you up a bit, remember even the most reputable tennis player’s make mistakes on the field, play incredibly badly and simply wish to leave the court.
This can apply to any hobby, sport, job or activity. If you play tennis every moment of your waking hours, burn out is unavoidable. In stead of burning out like this, you could indulge in some other activities like shopping, hanging out with friends, or being the couch potato and watch TV. This not only re-charges your mind but permits you to approach tennis afresh. Remember the quality of time you spend outside your court amidst such activities can be as precious as the time you spend playing.
Each tennis player has his own style of playing. While you should take your coaches advice, you need to ensure that you are doing what is comfortable for you. Things like your racquet, shoes and clothing ought to fit you best. Take time to nurture this. Completely imitating another player should never be done, even when the player happens to be your coach.
