try

I am standing in front of hurdle.

It's my first time. so I don't know how to jump and stretch my legs.

But If i don't try nobody makes me stand here.

So I should do.

I am sure.. I couldn't jump over the hurdle at first time but I will stand over the hurdle,

Then I can jump the next hurdle easily.
