I was taught one thing which I find very very important.

If you can't do it, fake it.

If you do not know how to dance, just fake it. Make believe to people that you know how to dance.

If you do not know how to speak good English, just fake it. Make believe to people that you are good in English.

Occasionally, I will be 'stucked'.

But I fake it.

And people will believe that I can do it.
