Hi Zhangjf7768,
What you need is not courage nor bravery. Save that when you are being placed in a dangerous environment, where you would need to display whatever you have been taught, or just make use of some common sense.
Before you can even go on practicing, you need to put trust into yourself! Learn to trust yourself that you would know how to protect yourself when you fall or, when your instructors are there to teach you all the breakfall. They wouldn't want you to break your neck as their reputation would be at stake right?
Tell yourself that you trust your body to make the right movement to avoid getting into any harm. Try it, and tell me. =) It works for me. Not sure for you though.
Wow, thankyou so much for your kind advices !
I will keep practising until I cross my psycho obstacles !
> TYING : Thanks so much for your post. I guess I lack the trust too. I realize trust does play an important part too !
