Do not go to teach others ,if you want to do it , then do it , others will automatically learn ,if the thing is really good

Acceptance of failure is very important

    If you want to go to higher level(want to move forward ) then first step will be , go and fight to achieve. For first attempt you may face failure, but accept that failure then only you will success. If you fail to accept that failure then fear will get developed and you will not go to second attempt.
   
    Acceptance of failure is very important. Once internally you accept that "I have weak points so I failed",
then you will start finding "What are the weak points that I have" , Work on that weak point , you will get the confidence , and that confidence will give you the energy for the Attempt NO. 2. Do the process repeatedly till you will not get the success.

    So first accept that "I failed because of my weak point."

    IF you will not accept it then you will never find your weak points and weak points will never become your strong point and you will never go for making the next attempt
