    The basics that i highly recommend you learn are…

    basic gripping technique
    learn how to hold your racket using the forehand and backhand grip. if  you are not holding the racquet properly, you won’t be able to  execute strong shots especially to your opponent’s baseline.

    basic footwork
    good  footwork allows good movement around the court. learn the basics of  covering the court to return your opponents’ shots!

    basic badminton strokes

    badminton serve
    a badminton rally starts with the serve. learn  the correct techniques to deliver good serves. good serves definitely give you an edge over your opponent right from the start of the rally.

    basic stance
    a  good stance sets you up to defend and attack effectively during a game! learn the offensive stance, defensive stance, and the net stance. you’ll find yourself at the top of your game when you use them correctly.

    remember this:   in order to become an  intermediate or advanced player, you must master the basics, make them  your habit,  then train and train and train. 

    once you get your basics right, learning those advanced or fancy badminton shots are just a matter of time!

    drop shots
    make sure you have a variation of shots in your games. drop shots are perfect to variate the pace of the rally.

    Their great contributions are they motivate us to look forward each in everyday with a smile and hope of good tomorrow. a lot of us normal people tend to look down our self, seing a pwd striving everyday to get on with their lives will motivate us to work harder and get inspire because we are more lucky enough to be normal and have a more successful life ahead. as an individual i was inspire by a lot of pwd who work hard each day to survive their day and i can see those beggar who can do more than what the pwd can but those beggar tend to rely on others for what they eat and for their tomorrow. why not be motivated by these people that despite of incompleteness they can still smile and achieve success.

    The 3 ways you build defenses against challenges to achieve the best quality of life is as follows:

    1. learning…you heard the old saying “you are what you eat”. well i believe you are what you read, find all the books you can find on personal growth and mastery over self. the most important person you need to learn about is yourself

    2. surround yourself with people who are successful or set the bar very high, it will challenge you to stretch yourself. furthermore, stay away from negative people who don't support you.

    3. live in the now, do not focus on the past, learn from it. additionally, you can plan for the future but don't live in the future because you’ll miss out on the joys of the present moment. remember when you are fully present, whatever you persue you will persue with unbelievable focus.
